Porsche 987 Cayman — 2004–2008

⚠ This dossier is incomplete. It came back without: verdict. It was written before runs checked for this, so the missing parts are simply absent rather than wrong.

https://bringatrailer.com/porsche/987-cayman/ · 467 completed auctions · 60 read in depth · compiled · 12 parts/memorabilia listings excluded

The figures below were computed by an earlier build of the analysis and do not carry later corrections to it. Refreshing this case file recomputes them from the same cars.

BaT files wheels, seats, engines and memorabilia under the same model page as the cars. 12 such listings were removed before any figure below was computed — e.g. No Reserve: 19×8.5″ and 19×10″ BBS Wheels for Porsche 987; No Reserve: Porsche 997 GT2 Carbon Bucket Seats; No Reserve: Rebuilt 2.7L M96 Flat-Six for Porsches.

The 987.1 Cayman has quietly become a $29k car with a $50k ceiling, and the whole spread is decided by mileage, colour and whether the seller bothered to borescope the engine.

The market

Across 467 completed BaT auctions the 987 Cayman sells 86.7% of the time at a median of $28,888 (mean $29,708), with the middle half of the market between $24,500 and $35,000 and full range $8,200–$66,500. That is a remarkably tight interquartile band for a 20-year-old car, and it tells you the model has settled into a mature, well-understood market rather than a speculative one. The trend is up: the last 12 months median $29,750 versus $25,250 the 12 months before, +17.8%. Calendar-year medians show the model peaked at $31,763 in 2021 and $31,750 in 2022, softened to $28,744 (2024) and $27,500 (2025), and has rebounded to $30,000 across 40 sales in 2026 to date.

Mileage is the dominant axis and it is close to linear until it isn't. Sub-20k cars cluster $39,000–$49,500 (No Reserve: 18k-Mile 2006 Porsche Cayman S 6-Speed at $39,000; 16k-Mile 2006 Porsche Cayman S 6-Speed at $40,500; 13k-Mile 2007 Porsche Cayman S 6-Speed at $44,000; Original-Owner, 11k-Mile 2007 Porsche Cayman S 6-Speed at $49,500). The 30k–70k band is the fat middle at $26,000–$36,000. Past 90k the floor drops hard — No Reserve: 2006 Porsche Cayman S 6-Speed at 103k made $15,500 and No Reserve: 2006 Porsche Cayman S 6-Speed at 93k with an undiagnosed knock made $15,500 — unless the engine has been rebuilt, in which case mileage almost stops mattering (No Reserve: 3.8L-Powered 2006 Porsche Cayman S 6-Speed, 128k miles, $41,000).

What moves money at the margin is documentation, not condition claims. The cars that beat their mileage band all showed a borescope, a DME over-rev report, or a credible Blackstone. The cars that missed reserve — 32k-Mile 2006 Porsche Cayman S 6-Speed at $24,250, 42k-Mile 2008 Porsche Cayman S 6-Speed at $28,750, 31k-Mile 2008 Porsche Cayman S 6-Speed at $31,750 — all had low miles and all refused a borescope. Commenter emjaferd's post-mortem on the last of those is the whole thesis: "Borescope or oil analysis would've increased the price and outcome of this auction." Conversely hachi_roku on the 18k-mile car: "Kudos to the seller here. DME report + a borescope? The peanut gallery has nothing to say this time."

Colour is the other lever and it is worth real money on this platform. The colour table shows Carmon Red Metallic at a $40,001 median (n=3) versus Arctic Silver Metallic at $27,625 (n=14) and Basalt Black Metallic at $24,445 (n=4). The two highest recent sales — 34k-Mile 2007 Porsche Cayman S 6-Speed in Nordic Gold at $51,000 and No Reserve: 2007 Porsche Cayman S 6-Speed in Dark Teal at $42,000 on 84,000 miles — are colour plays first and cars second. Base 2.7 cars, long the discount option, now trade almost level with S cars at equal mileage (2008 Porsche Cayman 5-Speed, 68k miles, $30,523; No Reserve: 36k-Mile 2008 Porsche Cayman 5-Speed, $29,750) precisely because they carry no bore-scoring risk.

Sub-20k indicated miles premium +35-70% over the 60-70k band

Original-Owner, 11k-Mile 2007 Porsche Cayman S 6-Speed made $49,500; 13k-Mile 2007 Porsche Cayman S 6-Speed made $44,000; 16k-Mile 2006 Porsche Cayman S 6-Speed made $40,500; No Reserve: 18k-Mile 2006 Porsche Cayman S 6-Speed made $39,000. Comparable 60-70k cars — 2006 Porsche Cayman S 6-Speed at 60k ($29,000) and 2007 Porsche Cayman S 6-Speed at 67k ($30,000) — sit $10-20k lower.

Rare or paint-to-sample colour premium +$10-15k

34k-Mile 2007 Porsche Cayman S 6-Speed in Nordic Gold Metallic, believed near one-of-one, made $51,000 — the highest recent sale, on a car with no service records, unknown shifter brand, and 22,000+ Range 1 over-revs. No Reserve: 2007 Porsche Cayman S 6-Speed in Dark Teal Metallic over Sand Beige made $42,000 on 84,000 miles with no maintenance history at all; commenter Shesgonnakillme: "This was at least a $15k bump just for the color." The stats agree: Carmon Red Metallic median $40,001 (n=3) versus Basalt Black Metallic $24,445 (n=4).

Borescope + DME report + oil analysis supplied in the listing premium +10-20%, and it is often the difference between sold and reserve-not-met

No Reserve: 18k-Mile 2006 Porsche Cayman S 6-Speed supplied both and sailed to $39,000. 2006 Porsche Cayman S 6-Speed (60k, Arctic Silver) supplied borescope images, DME, paint meter and cold-start video and made $29,000 against comparable mileage. The three reserve-not-met cars in this sample — 32k-Mile 2006 Porsche Cayman S 6-Speed ($24,250), 42k-Mile 2008 Porsche Cayman S 6-Speed ($28,750) and 31k-Mile 2008 Porsche Cayman S 6-Speed ($31,750) — all had genuinely low miles and all declined a borescope.

Professional big-bore rebuild (Flat Six Innovations / LN Engineering Nickies, IMS Solution) premium +$15-20k over an unrebuilt car of the same mileage, but roughly cost-neutral versus the rebuild invoice

No Reserve: 3.8L-Powered 2006 Porsche Cayman S 6-Speed with 128,000 miles made $41,000; 3.8L-Powered 2006 Porsche Cayman S 6-Speed with 93,000 miles made $40,001; 3.8L-Powered 2007 Porsche Cayman S 6-Speed with 122,000 miles made $36,500. Unrebuilt cars at that mileage make $15,500-$23,500. But commenter epaster on the 122k car: "Current bid is the cost of the engine rebuild lol" — the market pays for the work at cost, not at a premium.

3.6L-Powered 2007 Porsche Cayman S 6-Speed (X51 3.6 swap, Softronic tune with SAI file deleted, cannot pass California smog) failed to meet reserve at $27,750. Turbocharged 3.8L–Powered 2006 Porsche Cayman S 6-Speed, a $404rwhp TPC build with cats deleted, failed at $33,000; andy7777: "Really surprised it didn't hit at least $40,000." On 3.8L-Powered 2006 Porsche Cayman S 6-Speed the emissions-monitor exchange with HonkHonk ended with "as they say, 'buy the seller'. Thanks for saving me the money" and the car scraped reserve at exactly $40,001.

29k-Mile 2007 Porsche Cayman S 6-Speed, with Spokayman noting "nearly all of the panels have added paint depth" and a confusing $6,820 Aerokit/repaint receipt, made $31,750 — while 30k-Mile 2006 Porsche Cayman S 6-Speed with clean Carfax and original paint made $34,000. Original-Owner 2007 Porsche Cayman S 6-Speed, single owner but three disclosed accidents and possible welded quarter panel, made only $28,000 at 68k miles.

2006 Porsche Cayman S 6-Speed with 20,000 miles but 20" Champion wheels on 245/305 rubber made $36,000; commenter Bavarianchops post-sale: "If not for the lack of service and the wheels, it would've done 40K but 36K isn't bad…. the wheels are just wrong." Spokayman on 2006 Porsche Cayman S 6-Speed (55k, Basalt Black, H&R springs, subwoofer): "It's a harsh truth that mods, even good ones, do not add market value, and instead often devalue a car."

Manual transmission (either 5-speed base or 6-speed S) premium +30-50% versus Tiptronic, though the sample is thin

The analysed manual subset medians $30,000 (n=52). The two Tiptronic sales in the recent set are the two cheapest cars in it: No Reserve: 2008 Porsche Cayman S at $14,500 (74,539 miles) and No Reserve: Japanese-Market 2008 Porsche Cayman S at $15,250 (79,000 miles). 17k-Mile 2008 Porsche Cayman S Design Edition 1, a Tiptronic limited edition with 17k miles, still failed to meet reserve at $31,524 — a manual at that mileage would be $40k+.

2008 Porsche Cayman 5-Speed with 68,000 miles made $30,523 while several 60-70k S cars made $28,000-$30,000. No Reserve: 36k-Mile 2008 Porsche Cayman 5-Speed made $29,750 and 36k-Mile 2007 Porsche Cayman 5-Speed made $30,500. Commenter Primo2013: "The 2.7 Base is not subject to bore scoring like the S models" — buyers are pricing that in.

Known issues

majorCylinder bore scoring on the M97 3.4L (S models only)

raised on roughly 20 of the 60 threads reviewed — the single most recurrent topic

Dinodino on 2006 Porsche Cayman S 6-Speed (59k, Terracotta): "NO the Cayman S from this year does not use the M96 and this year is considered a high risk for bore score… the only way to protect investment is with a bore scope, period end of story." Caymangolfer on No Reserve: 2006 Porsche Cayman S 6-Speed (71k): "The 987 S has more bore score concerns than the base." On 3.6L-Powered 2007 Porsche Cayman S 6-Speed the 2025 inspection actually found light scoring in cylinder 2, and HSWEBB asked whether the ticking in the video was "the beginning of bore scoring noise" — the seller waved it off and the car did not sell.

Check: Insist on a borescope, ideally from the sump side. AnonUseryM9J4 on 2007 Porsche Cayman S 6-Speed (98k, Basalt Black): "The only way to know if you have bore scoring is to do a bore scope and it should be done from the sump side. Period." Supplement with a Blackstone taken on oil with 3,000+ miles on it (not 200), a cold-start video shot from behind the exhaust, and an oil-filter cut. Cylinder 6 and the drive-side thrust faces are the usual victims.

moderateIMS bearing — low actual failure risk on 987.1, but a magnet for false and unverifiable service claims

raised on 15+ of 60; misrepresented by the seller on at least three

On 2007 Porsche Cayman 5-Speed (89k, engine replaced) jasqaq wrote "The IMS in these engines is not serviceable without a complete disassembly of the engine, which they would not have done for free," and ApexHunter noted the invoice showed only long-block R&R; the seller admitted "I really should've just left that information about the IMS out." Same pattern on No Reserve: 2006 Porsche Cayman S 6-Speed (137k) where Spokayman forced the seller to concede only the flange/seal was likely done. Counterweight from bimmersnob on the same car: "the M97 engines use a larger OD bearing than M96 predecessors, so the 987/997 have a MUCH lower incidence of failure… IMS has never scared me away from a 987 or 997."

Check: Understand the architecture before you believe anyone: all 987.1 cars use the large non-serviceable bearing that requires splitting the case. If a seller claims 'IMS replaced,' demand the engine-out invoice with labour hours. A flange/seal swap or a direct oil-feed kit is a different, lesser thing.

majorAir-oil separator (AOS) failure — sudden, messy, and can hydrolock or destroy an engine

raised on 6 of 60, with one live failure discovered mid-auction

On 36k-Mile 2007 Porsche Cayman 5-Speed the seller pulled a live BaT auction after spotting white cold-start smoke; the diagnosis was a failed AOS, which was replaced and the engine scoped before relisting at $30,500. Spokayman on 2007 Porsche Cayman S 6-Speed (67k, Cobalt Blue): "When the AOS fails it can do so suddenly causing the intake system to flood with motor oil and billows of oil smoke out of the exhaust… This is not something you want to delay in replacing." 916Carl on the same thread: OEM part "around $140… It took me 3 hours and 15 minutes."

Check: Ask when the AOS was last replaced. Cold-start from behind, looking for a sustained white/blue cloud rather than a brief puff. If there is no receipt on a 15+ year old car, budget for it — roughly $632 at a shop or ~$140 in parts DIY.

moderateCooling system: plastic-impeller water pump, thermostat, coolant pipes

replaced or flagged on 10+ of 60

Nearly every well-prepared car in this set has a water-pump receipt: 2006 Porsche Cayman S 6-Speed (64k, Midnight Blue) had pump, belt, AOS, thermostat and intake gaskets all done November 2025 for ~$6,000 and made $34,000. phlat4 on 15k-Mile 2008 Porsche Cayman S 6-Speed listed the recommissioning bill for a garage queen: "oil change, serpentine belt, break fluid, transmission gear oil, coolant flush and some would recommend proactively replacing the water pump."

Check: Water pump receipt with date and mileage. bones302 raised the specific failure mode — brittle plastic impellers shattering and sending debris into the block. On No Reserve: 31k-Mile 2008 Porsche Cayman S 6-Speed a 17-year-old pump was still fitted and the dealer-seller simply said there were no leaks.

minorSagging headliner and rear hatch lining

present or already fixed on 12+ of 60 — effectively universal by now

Replaced on No Reserve: 2006 Porsche Cayman S 6-Speed (137k), 30k-Mile 2006 Porsche Cayman S 6-Speed, No Reserve: 2008 Porsche Cayman S 6-Speed (81k, Speed Yellow) and 2008 Porsche Cayman 5-Speed; still sagging on 32k-Mile 2006 Porsche Cayman S 6-Speed and 2006 Porsche Cayman S 6-Speed (59k). On No Reserve: 31k-Mile 2008 Porsche Cayman S 6-Speed the prior owner awesomekaptain volunteered that the "headliner was toast when I sold the car."

Check: Look at photos of the rear hatch lining specifically, not just the roof. Spokayman prices a professional replacement at around $1,000; Trademan8284 says DIY is feasible under $100.

moderateHVAC blend-door foam disintegrating and blowing out of the vents; sticky soft-touch switchgear

raised on 5 of 60, with worn climate switches on many more

32k-Mile 2006 Porsche Cayman S 6-Speed disclosed "foam emission is evident from the climate vents," then contradicted itself in a later video claiming the vents were clean — it failed to meet reserve at $24,250. 3.8L-Powered 2007 Porsche Cayman S 6-Speed disclosed "foam blowing through the vents which is a common malady." Worn or sticky climate switches noted on 44k-Mile 2006 Porsche Cayman S 6-Speed, 2006 Porsche Cayman S 6-Speed (104k) and others.

Check: Run the fan on high with the car cold and look for black foam flakes on the dash. Spokayman: patchable for ~$25 in parts plus labour, or a full fix requiring dash removal at serious cost. Also press every climate and centre-stack button for the tacky, peeling soft-touch coating.

moderateRear coil springs breaking, seized suspension hardware, rotted bump stops — all age-driven, not mileage-driven

raised on 4 of 60, but with severe consequences on two

On No Reserve: 3.8L-Powered 2006 Porsche Cayman S 6-Speed the seller found "a small piece of coil spring on the garage floor" — both rear springs had broken — and the subsequent teardown found seized parts requiring a full rear suspension rebuild. On 31k-Mile 2006 Porsche Cayman S 6-Speed a right rear shock was seeping and left unrepaired; Snowman87: "seeping or not, it needs to go." Dr_Outback on 13k-Mile 2007 Porsche Cayman S 6-Speed: "I bought a 5300 mile, 2011 Boxster S on here and the front and rear bump stops are rotted out" — a $2.7k repair. On 3.8L-Powered 2006 Porsche Cayman S 6-Speed a front strut had "slid down in the mount."

Check: Have the car on a lift and inspect both rear springs for cracks at the lower coils, check for strut seepage, and pull the boots to look at bump stops. Low-mileage cars are worse, not better.

moderateEmissions readiness: secondary air injection monitor won't complete

raised on 3 of 60, but a hard blocker in testing states

No Reserve: 2006 Porsche Cayman S 6-Speed (103k, Arctic Silver) could not complete the secondary air monitor after repeated drive cycles and sold for just $15,500. Commenter 777AIA offered the diagnostic shortcut: "Check to be sure that both fans are working. If one of the fans is out, you will get the secondary air monitor error… the mechanic said that was the fourth time he had seen the error with the fan." On 3.6L-Powered 2007 Porsche Cayman S 6-Speed the Softronic tune deleted the SAI file outright; the car did not sell.

Check: Get a scan showing all OBD-II monitors 'Ready' — not just 'no CEL.' A car with a cleared battery or a tune that deletes the SAI file will show 'Not Ready' and fail inspection.

moderateClutch, dual-mass flywheel and shifter cables

raised or serviced on 8 of 60

44k-Mile 2008 Porsche Cayman S 6-Speed needed a clutch at 44,000 miles; Dinodino flagged that neither the RMS nor the IMS seal was documented as done during that job. Avcat123 on 2008 Porsche Cayman S 6-Speed (110k, still on its original clutch): "Expect a clutch replacement soon! I'm on my second clutch at 106k." On No Reserve: 3.8L-Powered 2006 Porsche Cayman S 6-Speed the shifter cables broke twice.

Check: Ask for the clutch date and mileage; if the box has been out, ask whether the RMS was done and the IMS grease seal removed at the same time (Dinodino's standard question). Test the shift for vagueness — cables are a known break point.

minorDecade-old tyres on low-mileage cars

flagged on 6 of 60

15k-Mile 2008 Porsche Cayman S 6-Speed wore 2014-2015 Michelins; por356c: "After about 6-7 years, any tires useful, safe life is over. I know this because I am in the rubber business." 17k-Mile 2008 Porsche Cayman S Design Edition 1 was still on its original 2007 tyres and the seller had the dates wrong until Dr_Outback corrected him. Original-Owner, 11k-Mile 2007 Porsche Cayman S 6-Speed was on roughly 2015 rubber.

Check: Read the DOT date codes in the photos yourself; sellers get this wrong. Budget $1,200-1,800 for a set.

minorDME over-rev history from previous owners

discussed on 6 of 60

Spokayman on 2006 Porsche Cayman S 6-Speed (64k, Midnight Blue): "Range 4 & 5 overrevs can cause damage but in this case shows only 1 spark plug firing each… when only 1 is recorded it is an (electrical?) anomaly and not actually real." On 34k-Mile 2007 Porsche Cayman S 6-Speed he flagged "22,000+ range one revs" before other commenters concluded it was benign soft-limiter activity — the car still made $51,000. On 2006 Porsche Cayman S 6-Speed (55k) he caught a DME showing 959 engine hours against 55k miles: "it would have had to average over 57MPH including idling time."

Check: Pull the DME report and read it properly. Ranges 1-2 are near-meaningless; Range 3 is common; Ranges 4-6 matter, and a single-ignition count in Range 4/5 is usually an electrical artifact rather than a real event. Note the engine hours at which they occurred versus total hours.

Pre-purchase checklist

Ask the seller

  1. Has the engine been borescoped, and can you upload every cylinder image at full resolution? If not, will you allow me to arrange one at my cost before the auction ends?
  2. When was the air-oil separator last replaced, and do you have the invoice?
  3. Water pump, thermostat and coolant pipes — dates and mileages, with receipts.
  4. Can you supply a DME over-rev report and tell me the total engine hours it shows?
  5. If you claim the IMS bearing was replaced: which kit, by whom, and can I see the engine-out invoice with labour hours? (A flange/seal swap or an oil-feed kit is not a bearing replacement.)
  6. Was the rear main seal replaced and the IMS grease seal removed when the clutch was last done? What mileage was the clutch replaced at?
  7. Has the car ever been tracked, and can you account for all previous owners on that question? If there is a deep sump, oil cooler, GT3 control arms or a roll bar, explain who fitted them and why.
  8. Will the car pass an OBD-II readiness scan with all monitors 'Ready'? Can you run one now and post a photo of the screen?
  9. Are the original catalytic converters and factory exhaust included, and is the ECU tune reversible?
  10. Show me paint-meter readings on every panel, plus close-ups of any Carfax damage entry and the repair invoices.
  11. What are the DOT date codes on all four tyres?
  12. Do both rear coil springs look intact on the lift, and have the bump stops been inspected?
  13. How many keys, and is the original window sticker and service book present?
  14. Why are you selling, and how long have you owned it? (Cars flipped within a year with a few hundred miles added consistently invited scepticism in these threads.)

Walk away when

Budget

Driver-grade, $16,000-$24,000: 90k+ miles, or a Tiptronic, or an emissions/paint/accident problem. Expect to spend $3,000-6,000 immediately on cooling system, AOS, tyres and headliner, and accept unquantified bore-scoring risk on an S. The base 2.7 five-speed is the smart play in this band because the engine risk is materially lower.

Strong driver, $27,000-$33,000: 45,000-75,000 miles, clean Carfax, original paint, manual, with a documented water pump/AOS/clutch history and ideally a borescope. This is where the median lives and where most of the volume trades — 2006 Porsche Cayman S 6-Speed (64k, Midnight Blue, $6,000 of fresh service) at $34,000 and No Reserve: 2006 Porsche Cayman S 6-Speed (71k, Kelly Moss service) at $30,000 are the reference points.

Best-in-class, $38,000-$45,000: sub-30,000 miles, one or two owners, original paint verified by meter, full records plus borescope and DME. No Reserve: 18k-Mile 2006 Porsche Cayman S 6-Speed at $39,000 and 16k-Mile 2006 Porsche Cayman S 6-Speed at $40,500 define this tier.

Above $45,000 you are paying for colour or single-digit-thousand mileage — Nordic Gold at $51,000, Carmon Red at 11k miles for $49,500. That is collector money on a car whose all-time BaT high is $66,500; treat it as a discretionary purchase, not a value one.

A properly documented 3.8L Flat Six Innovations rebuild is worth $36,000-$41,000 regardless of odometer, but you are buying the rebuild at cost, so it makes sense only if you actually want the extra 40-50hp and the bore-scoring problem permanently solved.

Outliers

34k-Mile 2007 Porsche Cayman S 6-Speed

34k-Mile 2007 Porsche Cayman S 6-Speed $51,000

$51,000 is the top recent sale and roughly $17k above the 34k-mile trend line. Paint-to-sample Nordic Gold Metallic, believed one-of-one or near it, plus enthusiast mods (FVD deep sump, third radiator, GT3 control arms) endorsed publicly by a former owner in the thread. Notably the car had no service records, an unknown shifter brand, 22,000+ Range 1 over-revs, a rotor description that didn't match the photos, and a seller who declined to pull a wheel. Colour and a credible prior-owner voice bought over the top of all of it.

Original-Owner, 11k-Mile 2007 Porsche Cayman S 6-Speed

Original-Owner, 11k-Mile 2007 Porsche Cayman S 6-Speed $49,500

The mileage record-setter: 11,000 miles, one owner since new, Carmon Red Metallic over Natural Brown, complete provenance, and a DME report supplied on request that Spokayman judged good. Sold despite an unsympathetic cold-rev in the video, 10-year-old tyres and a non-DOT Fabspeed exhaust with the original gone.

No Reserve: 2007 Porsche Cayman S 6-Speed

No Reserve: 2007 Porsche Cayman S 6-Speed $42,000

$42,000 on 84,000 miles is roughly $12-14k above where that mileage normally lands, on a car with no paper service records at all, unbranded lowering springs, unknown clutch history and borescope photos so poor commenters couldn't read them. Dark Teal Metallic over Sand Beige did the work — Shesgonnakillme: "This was at least a $15k bump just for the color."

No Reserve: 3.8L-Powered 2006 Porsche Cayman S 6-Speed

No Reserve: 3.8L-Powered 2006 Porsche Cayman S 6-Speed $41,000

128,000 miles and $41,000 — nearly triple what a stock car at that mileage brings. A Jake Raby / Flat Six Innovations Stage II 3.8 with Nickies, IMS Solution, ~44k trouble-free miles since the 2021 rebuild, cats retained, and a thick file. Proof that a documented big-bore rebuild resets the mileage clock in buyers' minds. The seller conceded he had "way more in it than I can recoup."

No Reserve: 2008 Porsche Cayman S

No Reserve: 2008 Porsche Cayman S $14,500

The bottom of the recent market at $14,500 for 74,539 miles. Tiptronic, an oil analysis showing high iron that ScarySpikes called "a big red flag," a 2-3 foot rocker-panel gouge repaired with bondo on a generic receipt with no letterhead, and a failed prior Cars & Bids attempt. Everything that suppresses a 987 price, stacked in one car.

No Reserve: 2006 Porsche Cayman S 6-Speed

No Reserve: 2006 Porsche Cayman S 6-Speed $15,500

93,000 miles, a knock at idle that the seller declined to diagnose, no borescope, no oil analysis, no DME, and 15-year-old tyres — despite a genuinely rare PASM/Sport Chrono/adaptive sport seat spec. The market priced it as an engine-out car.

No Reserve: 2006 Porsche Cayman S 6-Speed

No Reserve: 2006 Porsche Cayman S 6-Speed $15,500

103,000 miles with an incomplete secondary air monitor that would not clear after multiple drive cycles, plus prior paintwork on the passenger door and fender and a notably smoky cold start. Unsellable in a testing state, and the price reflects it — bernie530 still called it "the deal of the century."

31k-Mile 2008 Porsche Cayman S 6-Speed

31k-Mile 2008 Porsche Cayman S 6-Speed $31,750

Reserve not met at $31,750 in November 2025 — then the same car, as No Reserve: 31k-Mile 2008 Porsche Cayman S 6-Speed, sold for $27,987 six weeks later. A clean natural experiment in what refusing a borescope costs: emjaferd's post-mortem was "Borescope or oil analysis would've increased the price and outcome of this auction," and the eventual buyer's mechanic found no scoring anyway.

Verdict

Several caveats. The transmission table reports a manual median of $30,000 (n=52) but gives no Tiptronic figure, so the manual premium I quote is inferred from three Tiptronic data points in the recent set — directionally right, statistically thin. The colour medians rest on n=3-5 for everything except Arctic Silver (n=14); Carmon Red at $40,001 and Seal Gray at $31,500 should be read as suggestive, not established. The 60 deep-analysed cars are all from October 2025 to August 2026, so the comment-derived issue frequencies describe how buyers behave now, not how the model behaved across the full 2017-2026 record. The mileage-versus-price table mixes stock cars, 3.8L rebuilds, turbo builds and stripped race cars in one column, which is why several high-mileage cars appear to defy the curve. Base 2.7 cars are heavily under-represented in the deep sample (7 of 60), so the claim that base cars now trade at parity with S cars is based on a handful of sales. Finally, everything attributed to commenters — Spokayman on DME ranges, Dinodino on bore-scoring risk, the various IMS explanations — is unverified opinion from strangers on the internet. It happens to be internally consistent and repeated across many threads by people who demonstrably own these cars, which is why I weight it, but none of it substitutes for a borescope you paid for yourself.

watch Underbidder placed much of the ladder — sailingbro placed 6 of 17 bids (35%) and did not win. Enthusiastic losing bidders are common; a very high share is still worth reading the thread for.

watch Closing bids came almost entirely from accounts with no posting history — 11 of 11 bids in the final 15 minutes (100%) came from accounts with under 25 lifetime likes (sailingbro, pirgi10, Craig_009, joshuairiye).

No Reserve: Modified 2007 Porsche Cayman 5-Speed
$22,750
· 75,000 mi · manual · carrara white
Well-executed and comprehensively modified 2.7 Cayman with honest seller engagement and strong bid price, but incomplete post-2022 maintenance documentation, non-serviceable 17-year-old IMS bearing, catless headers, and dual Carfax damage reports (2013/2014) present material risk that sophisticated buyer accepted at final price of $22,750.
Incomplete maintenance documentation post-April 2022 · Catless headers without emissions compliance path disclosed · Incomplete maintenance trail: large gap (26k miles over ~2 years) between last documented service (April 2022) and sale with vague claims of in-house maintenance; no records provided · Catless headers create re-sale friction and potential compliance issues in states with emissions testing
3.6L-Powered 2007 Porsche Cayman S 6-Speed
Reserve not met
· 79,000 mi · manual · carrara white
Impressive X51-swapped platform hindered by bore scoring, emissions lock-out, and unresolved engine noise—premium for the upgrade but reserve protection suggests buyer and seller still far apart on risk-adjusted value.
Bore scoring detected · Cannot pass California emissions test · Emissions compliance issue restricts resale to out-of-state buyers only · Engine swap from 2004 911 Carrera (77k miles on donor) paired with 987 electronics and software—complex integration
2006 Porsche Cayman S 6-Speed
$36,000
· 20,000 mi · manual · arctic silver metallic
A well-preserved 2006 Cayman S with concerning gaps in first-ownership documentation and unresolved IMS uncertainty, ultimately held back by non-original ill-fitting wheels and a seller who lacked formal inspection diligence, yet still achieved strong market value on handling reputation and low mileage alone.
Non-original wheel and tire setup · IMS bearing concerns unresolved via formal inspection · No formal pre-purchase inspection when current owner acquired car in 2016, despite age (10 years old at time) · First owner never identified; gap in ownership documentation for entire first decade
2006 Porsche Cayman S 6-Speed
$34,000
· 64,000 mi · manual · midnight blue metallic
Well-maintained, cosmetically excellent 2006 Cayman S with strong provenance and recent major service, but prior rapid sale history and ongoing overrevving incidents suggest proceed with extended PPI and mechanical inspection before closing.
Car previously sold on Cars and Bids less than a year ago for $28,000; now sold for $34,000 after $6,000 service—suggests potential rapid flip · Overrevving history indicates previous driver(s) with poor mechanical sympathy
No Reserve: 2006 Porsche Cayman S 6-Speed
$30,000
· 71,000 mi · manual · carrara white
Well-documented single-owner 987.1 Cayman S with recent major service and clean history, but bore scoring concern was raised and only partially addressed through seller's videos rather than professional compression/scope testing.
Bore scoring concern · Seller initially did not provide cold start video focusing on exhaust until specifically requested, raising initial buyer concern about bore scoring · No DME report available despite buyer request
3.8L-Powered 2006 Porsche Cayman S 6-Speed
$40,001
· 93,000 mi · manual · carmon red metallic
Meticulously documented 3.8 track build with proven performance but permanently catless configuration, unresolved emissions-monitor diagnostics, and a 2023 engine rebuild that's both a strength (comprehensive) and a red flag (why was it needed so soon?) make this a specialist's car only—perfect for non-testing-county enthusiasts, risky for anyone who needs street registration.
Catless configuration fails emissions testing · CEL behavior and emissions monitor readiness unknown · Catless configuration is permanent barrier to registration/use in emissions-testing states, yet car is being sold in Scottsdale, Arizona (non-testing county). Buyer must verify their own county/state requirements. · CEL status and OBD-II monitor readiness never scanned or documented. Seller became defensive when asked technical diagnostics questions, suggesting lack of due diligence.
2007 Porsche Cayman 5-Speed
$19,250
· 89,000 mi · manual · black
A well-driven 2007 Cayman with full engine replacement and claimed-but-unverifiable IMS service, offered by an honest but physically disabled seller who failed to adequately document critical work and resisted pre-sale inspection, ultimately selling to a PCA member at a fair market price despite red flags that would have benefited from independent verification.
Engine replacement undisclosed in original listing; seller added IMS mention later · IMS bearing service unverified and possibly not performed · Engine replacement not mentioned in initial listing title or opening description; discovered only through comment thread inquiry · IMS bearing service claimed but completely unverified with zero documentation; shop has closed/relocated and owner unreachable
3.8L-Powered 2007 Porsche Cayman S 6-Speed
$36,500
· 122,000 mi · manual · speed yellow
A comprehensively rebuilt, well-documented Speed Yellow Cayman S with excellent dual-purpose credentials and premium internals, but unproven in real-world miles post-rebuild and hammered at a price that barely exceeds the engine rebuild cost alone, signaling the market's skepticism of heavily modified Porsches regardless of build quality.
2017 Carfax accident report noted; seller describes as 'very minor damage to right-rear area' but impact occurred 9 years prior to sale · Bumper cover distortion and aluminum brace repair from undisclosed track incident not mentioned in initial description
2007 Porsche Cayman S 6-Speed
$30,000
· 67,000 mi · manual · cobalt blue metallic
Desirable 987.1 Cayman S with comprehensive service history and clean Carfax sold at fair market value, but flagged AOS and CV boot issues mean the new owner will face near-term maintenance costs exceeding $1,400 if addressed promptly as expert commenters recommend.
Air Oil Separator (AOS) flagged for future monitoring · Right rear and inner CV boot leakage · Model year correction needed (listing originally said 2006, corrected to 2007 per Carfax and seller) · Arizona odometer exemption for vehicles 2010 or older means true mileage cannot be fully verified by state agencies
2008 Porsche Cayman S 6-Speed
$23,500
· 110,000 mi · manual · meteor grey metallic
Well-maintained two-owner California Cayman S with clean history and comprehensive service records, but sold at $23,500 without critical pre-purchase diagnostics (borescope, compression) despite known IMS bearing and clutch vulnerability in the M97 generation—buyer is betting on preservation-quality ownership rather than prior deep inspection.
no borescope inspection performed · no compression or leakdown tests done as pre-sale prep
No Reserve: 2006 Porsche Cayman S 6-Speed
$15,500
· 103,000 mi · manual · arctic silver metallic
Clean, well-maintained 987.1 Cayman S with a secondary air monitor emission fault that remains undiagnosed despite dealer troubleshooting, restricted to out-of-state sale and priced accordingly, but mechanically sound underneath if the buyer can resolve the emissions readiness issue post-purchase.
secondary air system monitor incomplete · passenger-side door and fender prior paintwork · emissions system failure prevents California sale, restricts buyer pool significantly · secondary air system monitor will not complete despite dealer attempts and multiple drive cycles
20k-Mile 2008 Porsche Cayman 5-Speed
$28,500
· 20,000 mi · manual · black
A well-preserved low-mileage 987.1 with solid provenance and recent refreshes, but the garage-queen history and lack of a driving inspection create unquantified risk around clutch durability and dormant component reliability despite the clean title.
Low mileage garage queen concerns · Clutch reliability concern on prior ownership · Multiple ownership despite low mileage (garage queens are high-maintenance) · No driving video provided despite request from bidder pete_agler
No Reserve: 2006 Porsche Cayman S 6-Speed
$22,987
· 89,000 mi · manual · guards red
Well-optioned 987.1 with rare PASM and strong recent maintenance history undermined by severe PPF degradation, murky Copart origin with no pre-ownership records, and evidence of prior bumper damage repaired without proper documentation—sold fairly at $22,987 given cosmetic and service-history red flags despite excellent specification and seller transparency.
Severely degraded paint protection film (PPF) · Front bumper damage and repair history · Vehicle sourced from Copart auction (salvage/fleet/trade-in hub) with no pre-purchase inspection performed · Seller acquired from Copart over winter with minimal ownership (only ~100 miles added)—very quick flip
Turbocharged 2006 Porsche Cayman S 6-Speed Track Car
$32,500
· 38,000 mi · manual · lapis blue metallic
A meticulously tracked 2006 Cayman S with a cost-effective turbo build, proven track credentials, and transparent owner maintenance records that sold strongly at $32.5k despite title/registration ambiguity and expired safety certifications.
Harness and seat certification expiring · Limited photographic documentation · Vehicle sold on bill of sale despite having title available; registration status unclear and no record of last registration year · Safety equipment (harness and seat) certifications expired well before auction (2024 and 2022 respectively)
No Reserve: 18k-Mile 2006 Porsche Cayman S 6-Speed
$39,000
· 18,000 mi · manual · black
A methodically maintained, low-mileage 987.1 Cayman S backed by proactive diagnostics (DME, borescope) and an owner's track record of precision engineering, sold at fair market for the condition and documentation provided.
No Reserve: 2007 Porsche Cayman S 6-Speed
$42,000
· 84,000 mi · manual · dark teal metallic
A cosmetically spectacular and tastefully modified 987.1 Cayman S in a genuinely rare color combination sold primarily on eye appeal and fresh service assurances rather than complete maintenance history or documentation, at a price that reflects color premium more than mechanical confidence.
Borescope documentation quality · Missing maintenance records · No maintenance history documentation provided despite 84k miles · Borescope photos poorly presented with outdated camera date, raising questions about documentation reliability
No Reserve: 2006 Porsche Cayman S 6-Speed
$22,000
· 137,000 mi · manual · arctic silver metallic
Well-maintained 137k-mile Cayman S with solid recent service history and proactive seller, but IMS bearing work is ambiguous (likely only flange/seal replaced, not bearing), and lack of diagnostic reports (DME, borescope, oil analysis) leaves some engine condition questions unanswered at a final bid of $22k.
IMS bearing status unclear · Front tires showing cracks · IMS bearing work may not have been what seller initially claimed—specialist commentary suggests likely only flange/seal replaced, not bearing itself, creating ambiguity about engine condition · no DME computer report available despite $400 dealer quote, limiting diagnostic visibility into engine health
Original-Owner 2007 Porsche Cayman S 6-Speed
$28,000
· 68,000 mi · manual · carmon red metallic
Original-owner 2007 Cayman S with manageable low-speed damage history and recent preventative maintenance, but marred by a 17-year service documentation gap, vague details on quarter-panel repair methods, and lack of any dealership IMS inspection—sold at $28k to a buyer betting on the seller's long stewardship and no-event recent history outweighing the incomplete paper trail.
Three accident incidents with body damage · Extensive service history gap (17 years, 60k miles) · Incomplete service records despite original ownership—17-year, 60k-mile gap in documented maintenance · Three separate accidents over ownership period, seller initially did not volunteer full damage history; details only emerged when pressed
No Reserve: 36k-Mile 2008 Porsche Cayman 5-Speed
$29,750
· 36,000 mi · manual · arctic silver
A rare low-mileage 987.1 Cayman with documented prior-owner stewardship, factory paint, and a clean DME report that sold at fair market value despite some initial listing errors that were quickly corrected.
title/headline initially said 6-speed instead of 5-speed (corrected during auction) · color was initially listed as GT Silver instead of Arctic Silver (corrected by BaT after commenter catch)
36k-Mile 2007 Porsche Cayman 5-Speed
$26,000
· 36,000 mi · manual · guards red
Well-maintained, low-mileage example with documented hail damage and repaint, sold quickly by a non-communicative seller who declined to provide mechanical verification, ultimately fetching $26k from a determined bidder despite red flags around transparency.
Hail damage and repaint history · Non-tamper-resistant odometer note on title · Seller purchased car in 2025 and added only 585 miles before listing for sale within months, raising questions about motivation and mechanical confidence · Seller declined to provide cold-start video despite multiple requests from commenters, which commenters viewed as evasive
No Reserve: 2006 Porsche Cayman S 6-Speed
$15,500
· 93,000 mi · manual · arctic silver metallic
Exceptionally rare and well-optioned 987.1 with undisclosed engine internals damage that may or may not be catastrophic, sold at no-reserve and below market specifically because the seller refused diagnostic clarity, betting the spec and condition of everything else would overcome a ticking time-bomb powertrain.
Engine knocking at idle · Brake wear message and brake light stays on · Engine knocking never diagnosed (no bore score inspection, no dyno, no oil analysis, no DME report); seller refuses professional diagnosis · UK export/re-import in 2015-2018 suggests potential undisclosed damage or regulatory issues abroad
16k-Mile 2006 Porsche Cayman S 6-Speed
$40,500
· 16,000 mi · manual · arctic silver metallic
A genuinely single-owner, garage-kept 2006 Cayman S with impeccable specialist service history and preventive IMS work, but no borescope confirmation and still-original brakes/suspension raise questions about long-term reliability for an active buyer—priced fairly at $40.5k given the low mileage and strong provenance.
Carfax initially showed conflicting sale history; seller clarified with original invoice (12/11/2006) and explained Carfax error—verified as single-owner, one subsequent sale to current dealer · brake pads, suspension bushings, and seals all original—no service records documenting brake/suspension overhaul, which commenters noted would be prudent before long-term use
2006 Porsche Cayman S 6-Speed
$22,750
· 104,000 mi · manual · basalt black metallic
A 104k-mile 987.1 Cayman S with comprehensive recent service history and clean cylinder walls, substantially compromised by undisclosed accident damage across three panels, extensive undercarriage scraping, lowest coilover settings, an undisclosed lien, and a hastily remedied CEL—marketed as 'driver quality' but bearing marks of hard use and deferred cosmetic resolution.
Extensive front-end damage and scraping · Coilovers set to lowest setting with damaged undercarriage · Active lien amount kept confidential by seller despite multiple buyer inquiries; unclear if reserve protects buyer if final sale price falls below lien amount · Extensive paintwork history across multiple panels suggesting previous accident(s) not fully detailed
2006 Porsche Cayman S 6-Speed
$25,250
· 59,000 mi · manual · arctic silver metallic
A visually appealing, low-mileage 987.1 with desirable trim but hobbled by absent mechanical documentation, high bore-scoring risk, time-dependent service neglect, and cosmetic damage—attractive spec undermined by critical due-diligence gaps that the new owner will now have to investigate and remedy.
passenger-side door damage · bore scoring risk · No service records or receipts provided despite seven years of ownership (2019-2026); seller claims car 'hasn't needed service' which is inconsistent with manufacturer time-based maintenance intervals · No borescope inspection despite this model year (2006) being high-risk for bore scoring, especially given cold-climate (Illinois) first ownership
44k-Mile 2008 Porsche Cayman S 6-Speed
$36,000
· 44,000 mi · manual · macadamia metallic
A cosmetically rare, low-mileage 987 with documented rear damage history, undisclosed IMS/RMS service gaps, and seven prior owners that sold on color appeal to a niche buyer at $36k despite moderate mechanical red flags.
IMS grease seal not confirmed removed during clutch replacement · Rear Main Seal (RMS) replacement not documented · Multiple owners (7 total) in relatively short time spans suggest car may have been flipped; commenter Dinodino noted this pattern · Clutch replaced at 44k miles, which is early; raises questions about prior owner driving habits or potential undisclosed issues
29k-Mile 2007 Porsche Cayman S 6-Speed
$31,750
· 29,000 mi · manual · arctic silver metallic
Low-mileage 2007 Cayman S with excellent spec and documented history is undermined by widespread repainting, undisclosed damage scope, vague repair receipts, and long dormancy—buyer is betting on mechanical integrity but inheriting cosmetic and historical ambiguity.
Multiple panel repaints with elevated paint depth readings · July 2012 minor damage on Carfax · Multiple panels repainted with elevated paint-depth readings suggesting prior accident or damage beyond disclosed July 2012 'minor damage' · Aerokit receipt and R-style graphics timeline inconsistent or unexplained—seller admits confusion about what was actually done
No Reserve: 3.8L-Powered 2006 Porsche Cayman S 6-Speed
$41,000
· 128,000 mi · manual · seal gray metallic
A comprehensively rebuilt 3.8L sleeper Cayman with factory bones, professional engine internals, seven figures in claimed spend, and honest documentation—but recent major pre-sale repairs (rear suspension, diagnostics) and multiple front-end damage episodes leave lingering questions about underlying condition and whether all costs were truly captured.
Front bumper cover damage and multiple repaints · Broken shifter cables (2x) · Front bumper damage and multiple repaints suggest parking lot incidents or careless ownership period · Unexplained O2 sensor code required ~$4k diagnostic work, indicating potential electrical gremlins
47k-Mile 2006 Porsche Cayman S 6-Speed
$31,500
· 47,000 mi · manual · seal gray metallic
A meticulously maintained first-generation Cayman S with exceptional low mileage and documented service history owned by an 80-year-old enthusiast, undermined only by a non-functional aftermarket audio system and minor cosmetic dings that did not prevent strong bidding competition.
Bose surround sound system not functional · Carfax shows four owners but seller claims two private owners; discrepancy in ownership count requires clarification · Bose surround sound advertised in essentials but not operational; requires reconnection work
32k-Mile 2006 Porsche Cayman S 6-Speed
Reserve not met
· 32,000 mi · manual · arctic silver metallic
A nicely equipped manual Cayman S with suspiciously low miles for its condition and zero service documentation, which cost the seller the sale when bidders collectively decided the undisclosed mechanical gamble wasn't worth the reserve price.
HVAC foam emission from vents · Brake rotor scoring · No service records or maintenance documentation provided despite 32k miles of claimed gentle use · No bore scope or oil analysis offered despite commenters repeatedly requesting these as standard reassurance on 3.4L 987 engines with IMS bearing concerns
17k-Mile 2008 Porsche Cayman S Design Edition 1
Reserve not met
· 17,000 mi · tiptronic · black
A low-mileage, documented Design Edition 1 in showroom condition with all factory accessories intact, marred only by 16-year-old original tires and a minor tire-width spec discrepancy that left bidders $31.5k short of reserve.
Tire age concern · Tires are original 2007 vintage, 16+ years old despite low mileage, indicating storage but requiring replacement regardless of condition · Seller initially gave incorrect information about tire age then corrected it after being challenged by commenters
2006 Porsche Cayman S 6-Speed
$26,000
· 55,000 mi · manual · basalt black metallic
A well-documented 987.1 Cayman S with recent bore scope and DME validation, a clutch refresh, and the harder-to-fail third-gen IMS bearing, but undermined by uncertain modification authenticity, potential odometer/DME inconsistency, and a short flipper trajectory that may have suppressed final price despite buyer-friendly fundamentals.
DME/overrev history interpretation discrepancy · Right rear damage and repair history · Exhaust brand and material unverified despite being listed as premium Fabspeed titanium · DME report timing unclear—no date or current mileage stamped on report provided; engine hours (959) seem inconsistent with 55k miles
2006 Porsche Cayman S 6-Speed Track Car
$30,500
· 77,000 mi · manual · metallic black
Well-built track car with quality components and strong provenance that changed hands at a rational price, but the replacement engine's exact origin and prior failure cause remain obscured, the $100k build claim is speculative, and a 2015 Carfax notation was initially omitted from disclosure.
Replacement engine origin uncertainty · No DME report available · $100k build-cost claim is unverified and disputed by experienced builder Rjstlstc as exaggerated or overpriced; seller defers to previous owner's claim and later suggests cost included car acquisition · Engine source (987.1 vs 987.2) uncertain even at time of sale; seller unsure despite owning since 2019
No Reserve: Japanese-Market 2008 Porsche Cayman S
$15,250
· 79,000 mi · automatic · white
A well-maintained Japanese-import one-owner Cayman S with verified history and proven mechanical health, complicated by non-standard exhaust tuning, backup-camera retrofit provenance gaps, and US federalization barriers that likely depressed North American bidding and pricing.
Exhaust system tuning status unclear · Japanese market vehicle requiring EPA federalization for US registration (not 25 years old yet); seller correctly disclaims responsibility but creates barrier for US buyers · Aftermarket exhaust headers without catalytic converters present; original factory exhaust status uncertain and being sourced from Japan with no guarantee of availability
2007 Porsche Cayman S 6-Speed Track Car
$39,250
· 33,000 mi · manual · blue wrap on black
A professionally built six-figure race Cayman with a documented 2011 accident history, missing documentation, and post-build modifications that obscure its original engineering—sold at a discount beneath its Racing Junk asking price to a committed bidder who understood the package and its track-day purpose.
Front airbag deployment and multi-point damage · Wheel damage · No title or registration; sold on bill of sale only · 2011 accident history with airbag deployment not emphasized in listing headline
No Reserve: 2008 Porsche Cayman S
$14,500
· 74,539 mi · tiptronic · arctic silver metallic
Attractive no-reserve 987.1 Cayman S at low six figures, but elevated iron in recent oil analysis warrants pre-purchase PPI inspection to rule out bore scoring, and the hastily-repaired structural rocker panel repair (initially misrepresented, receipt late and generic) combined with incomplete disclosure history on Cars & Bids listing suggests buyer should verify mechanical condition thoroughly before committing.
elevated iron in oil analysis · passenger rocker panel damage and repair · Rocker panel repair receipt initially missing, only provided late in auction after repeated requests from multiple commenters · Generic repair receipt lacking business letterhead, address, or phone number raised credibility questions
48k-Mile 2008 Porsche Cayman 5-Speed
$26,500
· 48,000 mi · manual · arctic silver metallic
A low-mileage 2008 base Cayman with strong bones, recent service, fresh cosmetic work to address prior quarter-panel damage, and no documented major deferred maintenance—a solid entry-level manual Porsche marred only by the lack of proactive IMS bearing address and confirmed clutch/water-pump history.
right rear quarter panel previously refinished to substandard level · IMS bearing not replaced and requires engine removal if preventive action desired · missing documentation for common preventive maintenance items (clutch, water pump, air oil separator, main belt) · IMS bearing never replaced and not being proactively addressed despite known risk profile on 987.1
No Reserve: 2006 Porsche Cayman S 6-Speed
$30,000
· 62,000 mi · manual · cobalt blue metallic
Desirable low-mileage 987.1 with proactive IMS preventive work and strong service history, but marred by paint defects, a quick flip narrative, and aftermarket modifications whose reversibility is unclear—solid bones, cosmetic and electrical gotchas.
failing clear coat on multiple panels · aftermarket fog light spars with unknown wiring condition · seller acquired car only ~2 months prior to auction (purchased in late 2025, listing early 2026) · quick liquidation due to overseas property purchase raises questions about inspection depth
2007 Porsche Cayman S Race Car 6-Speed
$36,500
· 37,000 mi · manual · guards red
Professionally built race car with credible track pedigree and strong performance potential, but hampered by unknown engine history, mileage data integrity issues, incomplete tuning documentation, and unresolved questions about post-swap validation that a serious buyer would want resolved in PPI before committing.
Mileage inconsistency · Engine sourced from donor car with unknown history · Mileage inconsistency flag on Carfax (2020); actual mileage unknown · Engine is used/rebuilt from donor car with unknown prior history or compression/bore status; no PPI engine work documented
30k-Mile 2006 Porsche Cayman S 6-Speed
$34,000
· 30,000 mi · manual · basalt black metallic
A credibly documented, low-mileage example from a single-generation collector's garage with the manual, black-on-black, sport-seat spec that drives fierce competition; minor cosmetic wear and lack of third-party inspection are secondary to the clean title, service trail, and provenance story.
Service records lumped in one photo, not itemized (Spokayman raised this; seller promised closeups but exact work dates/mileage unclear from thread) · No DME report or borescope provided (seller declined to obtain, citing purchase from elderly collector)
2006 Porsche Cayman S 6-Speed
$29,000
· 60,000 mi · manual · arctic silver metallic
A well-documented, low-mileage 987.1 Cayman S with transparent seller disclosure and solid service history marred only by a disputed Carfax damage entry and minor questions about belt inspection philosophy that ultimately sold at market-appropriate $29k to a local buyer.
Carfax damage entry (left front minor damage) appears in June 2025 despite seller's claim of clean history; dispute filed but not removed from report · Timing of door replacement unclear—seller initially stated 'driver door' was replaced but clarified it was only the 'left window switch' that was replaced; potential confusion or inconsistency in communication
42k-Mile 2008 Porsche Cayman S 6-Speed
Reserve not met
· 42,000 mi · manual · macadamia metallic
Stunning color and low miles undercut by absence of borescope despite known 987.1S bore-scoring risk, unverified zero-oil-consumption claim, and eight prior owners across 18 years, making this a premium cosmetic buy that requires independent bore inspection before commitment.
no borescope inspection performed · no oil analysis or DME report provided · no borescope inspection despite known 987.1S bore-scoring risk · zero-oil consumption claim unverified by oil analysis
Turbocharged 3.8L–Powered 2006 Porsche Cayman S 6-Speed
Reserve not met
· 42,000 mi · manual · seal gray metallic
A genuinely rare and well-executed turbo-swapped 987.1 built for tracked use and still docile enough for street duty, hobbled at sale by cat deletion, missing provenance on the original engine, and a seller unprepared to negotiate despite reserve not being met—ultimately staying in the family.
Catalytic converters deleted; not included with sale · IMS bearing status of replacement M97 engine unknown · Multiple unrelated documents accidentally uploaded (transmission rebuild invoices from 2011, Snow Performance methanol injection invoices that belong to seller's 1991 911 Turbo, not this Cayman) · Engine swap and extensive modifications performed immediately after original owner's purchase in 2006, yet no stock parts or engine included with sale
No Reserve: 31k-Mile 2008 Porsche Cayman S 6-Speed
$27,987
· 31,000 mi · manual · guards red
A genuinely low-mileage, carefully stewarded Cayman S with sound mechanicals (confirmed post-sale), marred only by the dealer's initial evasiveness on dashboard warning and slow production of promised oil-analysis documentation, though final owner verification suggests it was overblown concern.
Red General System Fault Warning light illuminated during video walkthrough · Bore scoring risk not definitively ruled out · Dealer (Collectible Classics) is a high-volume seller with some reputational concerns per ANAfoundry's comment about negative reviews upon 'deep dive,' though dealer claims 4.8/5 Google rating with 400+ reviews · Bore scope was not performed despite being a known concern for M97 engines; reliance on oil analysis alone rather than visual inspection
13k-Mile 2007 Porsche Cayman S 6-Speed
$44,000
· 13,000 mi · manual · arctic silver metallic
Exceptionally well-optioned, low-mileage 987.1 with perfect documentation and no accident history, but seller's evasion on bore-scoping and bump-stop condition—both known weak points—left money on the table despite strong final price.
Bore scoring concern raised by commenters · Bump stop condition unknown · 2022 invoice documented RMS seepage but repair was deferred; seller later claimed no current leak without independent confirmation until re-inspection · seller declined proactive bore-scope inspection despite multiple informed commenters raising it as standard due diligence for this engine
Turbocharged 2006 Porsche Cayman S 6-Speed Track Car
$30,250
· 58,000 mi · manual · black with gray vinyl wrap
Ambitious turbocharged 987 with underdocumented engine work, missing emissions hardware, no seller track experience, and a lien; won by a bidder with zero BaT history at $30,250 despite significant technical questions from seasoned collectors.
Missing original catalytic converters · Uneven tire wear and track tire limitations · No documentation from turbo installation or previous owner; work supposedly done by HG Performance but unverified · Missing OEM catalytic converters; car cannot be registered in California without them, limiting buyer pool significantly
Original-Owner, 11k-Mile 2007 Porsche Cayman S 6-Speed
$49,500
· 11,000 mi · manual · carmon red metallic
A meticulously preserved single-owner 11k-mile Cayman S in desirable rare colors, fully transparent on modifications and service history, but the combination of extreme low mileage, extended storage, and cold-engine revving in video present latent M97-engine concerns (IMS bearing, bore scoring) that a pre-delivery borescope inspection would prudently address before taking possession.
Cold engine revving in video · Tire age · Low mileage (11k miles) combined with long storage periods may increase IMS bearing and bore scoring risk despite ceramic coating and garage storage · Original Alpine head unit recently installed (not original to car as sold)
36k-Mile 2007 Porsche Cayman 5-Speed
$30,500
· 36,000 mi · manual · arctic silver metallic
Low-mileage manual Cayman with transparent ownership history and recently diagnosed/repaired air-oil separator defect, backed by full service records and fresh maintenance, though the mid-auction withdrawal raises questions about what else might be lurking.
Air-oil separator failure · Auction withdrawn and relisted after discovering air-oil separator failure mid-auction suggests potential for other undiscovered issues
34k-Mile 2007 Porsche Cayman S 6-Speed
$51,000
· 34,000 mi · manual · nordic gold metallic
A genuinely rare, well-modded, single-owner-modified 987.1 Cayman S in a stunning one-of-one paint with clean history and solid provenance, marred only by the seller's evasiveness on modification details and minor specification inconsistencies, ultimately justified the strong final bid of $51k for collectors seeking manual-transmission color exclusivity and driving pedigree.
Seller declined to perform basic wheel-off inspections (calipers, rotors) citing showroom backed-up status, despite car being in transit to sale · Seller unable or unwilling to provide specifics on major modifications: Fabspeed install date, original exhaust disposition, shifter brand, installation dates for other upgrades
No Reserve: 2007 Porsche Cayman S 6-Speed
$23,987
· 105,000 mi · manual · arctic silver metallic
Well-serviced 987.1 with comprehensive 2025 refresh and solid provenance, but undisclosed IMS bearing status, 7-year service record gap, 9-year-old tires, unresolved rocker panel and bumper paint concerns, and seller evasion on final inspections create meaningful deferred-risk exposure for the $23,987 winning bid.
IMS bearing status unknown · Service records gap 2007-2013 · 7-year gap (2007–2013) in available service records despite claim of meticulous maintenance · IMS bearing replacement status undocumented; critical wear item for this generation never confirmed addressed
15k-Mile 2008 Porsche Cayman S 6-Speed
$40,250
· 15,000 mi · manual · meteor gray metallic
A pristine low-mile manual Cayman S from a credible dealer that checks every box on paper, but the new owner inherits expensive tire replacement, unperformed bore-score testing, absent service records, and the inherent risk of a long-garage-queen recommissioning all at $42k total cost including buyer's fee.
Tires aged 10-11 years old · Missing service records · Only one key provided (per seller response to emigre74) · No service records available; seller relies only on Carfax
2008 Porsche Cayman 5-Speed
$30,523
· 68,000 mi · manual · black
A well-documented base 987 manual with meticulous prior ownership and documented service marred only by recent parking-lot damage that the seller appears to have candidly disclosed, hitting market as a strong value proposition for enthusiasts seeking authentic engagement over marque status.
parking lot collision damage · parking lot damage not disclosed in carfax; seller explains no police report filed so carfax does not reflect it · aggressive performance driving shown in listing video may raise concerns about mechanical stress despite car's meticulous maintenance history
2007 Porsche Cayman S 6-Speed
$22,890
· 98,000 mi · manual · basalt black metallic
This is a well-optioned, recently serviced 987.1 with a clean title and supportive ownership history, but the seller's refusal to perform borescope inspection and the undocumented IMS bearing status during recent major engine work create material uncertainty about the car's internal engine health at 98k miles—a critical gap for this known-problem platform.
IMS bearing status unknown · AOS (air-oil separator) status unclear · No IMS bearing inspection or replacement documented despite major engine work (RMS, flywheel, clutch) in May 2024—known failure point on 987.1 models · No borescope inspection offered despite direct request; seller deflected with cold-start smoke test as substitute
No Reserve: 2008 Porsche Cayman S 6-Speed
$27,500
· 81,000 mi · manual · speed yellow
A low-mileage, well-serviced yellow 987.1 Cayman S with a clean DME report but odometer discrepancy history and conspicuous gaps in recent service transparency and pre-purchase inspection (no bore scope) that buyers compensated for by focusing on engine data and price discovery.
Odometer discrepancy on Carfax · No bore scope performed · Odometer discrepancy and TMU designation; required seller explanation and Carfax correction · Multi-state ownership history (Nevada, California, Washington, Arizona) over 17 years suggests frequent moves/flips
46k-Mile 2006 Porsche Cayman S 6-Speed
$28,000
· 46,000 mi · manual · speed yellow
A cosmetically well-executed Speed Yellow Cayman S that was flipped quickly with minimal driving and an undisclosed exhaust system, absent critical IMS/bore scope validation and factory steering wheel, yet sold at strong market price—suggesting color and condition masked underlying provenance gaps.
Only one key provided · Quick flip: sold on BaT June 2023, current owner purchased later same year, resold November 2025 with only ~900 miles added · Evasive early response: commenters noted 'no responding attitude' from seller regarding multiple questions
31k-Mile 2008 Porsche Cayman S 6-Speed
Reserve not met
· 31,000 mi · manual · guards red
Well-presented low-mileage 987.1 with solid provenance and service records, but seller's refusal to bore-scope or PPI the non-serviceable IMS bearing—combined with aged tires, a failed reserve, and minor discrepancies in answering drivetrain detail—signals underlying caution in the market.
Aged tires · IMS bearing unconfirmed · No bore scope performed despite non-serviceable IMS bearing concern raised early and prominently in comments · Seller declined PPI suggestion, only offered contact info for third-party inspectors
44k-Mile 2006 Porsche Cayman S 6-Speed
$30,500
· 44,000 mi · manual · seal gray metallic
Well-maintained 987.1 Cayman S with solid provenance, clean PPI, and oil analysis backing the seller's bore-scoring claims, though missing bore scope, owner count discrepancy, and PPF wear kept buyer competition limited and final price attractive for the local buyer who physically verified it.
Owner count discrepancy · owner count discrepancy between Carfax (6 owners per seller) and third-party VIN search (10 owners per bidder Jmk9911) · no bore scope performed despite 3.4L engine bore scoring being known concern in the model
31k-Mile 2006 Porsche Cayman S 6-Speed
$32,277
· 31,000 mi · manual · slate gray metallic
A genuinely low-mileage and well-sorted early manual Cayman S with excellent handling and remarkably preserved exterior, but purchased by the seller for quick resale, left with a seeping rear shock unrepaired, and lacking any bore scope or oil analysis despite living through cold Colorado and salty Northeast winters — good value at $32k if bore is clean, risky if not.
Right rear shock seeping · Extensive rock chips on rocker panels and lower areas · Buyer purchased to immediately resell — flipped within one month, adding fewer than 100 miles, signaling no confidence in car or quick-buck dealer play · Shock seeping but not replaced — seller chose not to address known defect before sale despite owning it pre-sale
No Reserve: 49k-Mile 2006 Porsche Cayman S 6-Speed
$28,750
· 49,000 mi · manual · arctic silver metallic
A meticulously maintained, low-mileage 987.1 Cayman S with minor cosmetic imperfections, no major mechanical red flags, but unaddressed known-issue risks (IMS retrofit, RMS documentation) that any buyer should inspect thoroughly before taking delivery.
Spark plugs last replaced November 2021 at 46,600 miles · IMS bearing retrofit not performed despite 987.1 being known risk year; seller relies on oil filter inspection only · No RMS documentation despite known RMS leaks being common on this model
50k-Mile 2006 Porsche Cayman S 6-Speed
$27,300
· 50,000 mi · manual · black
A low-mileage, well-specced 2006 Cayman S with recent maintenance and a rare package combo, but the seller's limited knowledge, short flipping timeline, inconclusive oil analysis, and unexplained odometer notation warrant a pre-purchase borescope and independent inspection before committing to the $27.3k final bid.
Clutch replacement at 15k miles · Blackstone oil analysis inconclusive due to low sample volume · Seller acknowledges he 'got it on a whim' and does not have detailed knowledge of the car's service history or modifications · No paint meter readings provided despite multiple requests
2007 Porsche Cayman S 6-Speed
$28,427
· 69,000 mi · manual · gt silver metallic
A cosmetically appealing but mechanically unverifiable 987.1 with tracked-car modifications, a decade-long service gap, and a seller unwilling to invest in simple diagnostics—sold to an aggressive bidder more committed than prudent.
Last recorded oil change over 10 years prior (September 2015 at 47,619 miles) · Deep-sump oil pan and suspension mods suggest tracking history but seller denies · Deep-sump oil pan and Tarrett sway bar installed, typically used for track duty, yet seller claims 'never tracked' without ability to verify prior owners · Last recorded oil change September 2015 (10+ years ago at 47.6k miles) — massive service gap with no documentation of intervening work
