A 20-year-old Cayman is no longer a cheap Porsche: the 987 median has climbed to $33,250 over the last 12 months (+18.8%), with base/S cars clustering around $30–36k and R/limited variants living in a separate $70–100k world.

The market
Across 666 completed BaT auctions the 987 Cayman has a sell-through rate of 87.2% — high, and consistent with a car that has an established price band buyers and sellers both understand. The all-in median sold price is $30,987 (mean $33,764), with the interquartile range running $25,000 to $39,000. That $14k spread between the 25th and 75th percentile is the real story: within the same nameplate you are choosing between a leggy base 2.7 with deferred maintenance and a documented, low-mile S or a special variant, and the market prices those very differently.
The trend is up and it accelerated recently. Yearly medians ran $25,575 (2019), $26,000 (2020), then jumped to $32,000 (2021) and $35,419 (2022) in the pandemic run-up, softened to $32,500 (2023) and $30,244 (2024), flattened at $30,500 (2025), and have snapped back to $36,000 across 69 sales in 2026 to date. The trailing-12-month median of $33,250 against $27,994 the prior 12 months (+18.8%) is a genuine step change, not noise — 2026 already has nearly as many sales as any full prior year. The top of the range has also stretched: 2026 has produced a $100,000 result where 2019's ceiling was $62,000.
What is actually moving the numbers is variant and documentation, not condition alone. The four most recent deep-analysed sales make the point cleanly: three 2006 Cayman S manuals with 20k, 64k and 71k miles landed at $36,000, $34,000 and $30,000 respectively — a $6,000 spread across a 51,000-mile difference, which tells you mileage is worth surprisingly little on an early S once you are past the collector threshold. Meanwhile a 15k-mile 2012 Cayman R with PDK made $79,618, roughly 2.2x the S money, and a commenter in that thread (Wmurray6400) noted he had just paid $70k for a 38k-mile black R — so the R market is deep and independent of the base car.
Bidding behaviour is telling. Both of the sub-$1,000-opening S cars (the $34,000 midnight blue and the $30,000 no-reserve Carrara white) climbed steadily with genuine multi-bidder competition in the final minutes; the $36,000 arctic silver car started slow below $10k and only ignited past $19k. Buyers are present but they are discriminating late, and they are discriminating on service records and originality. Bavarianchops summed up the $36,000 sale bluntly: "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." That is a stranger's opinion, but it is directionally consistent with the rest of the record.

What moves the price
Cayman R (and by extension the limited/hardcore variants) versus base/S premium +$40–50k, roughly 2.2x an equivalent S
15k-Mile 2012 Porsche Cayman R sold $79,618 against three 2006 Cayman S manuals at $36,000, $34,000 and $30,000 in the same three-week window. A commenter in the R thread reported paying $70k for a 38k-mile R, corroborating that the R floor sits near $70k regardless of mileage.
Documented recent major service (water pump, AOS, thermostat, belts, plugs, fluids) premium +$4–6k on a $30k car
The 64k-mile midnight blue S had ~$6,000 of November 2025 work (water pump, drive belt, AOS, thermostat, intake manifold gaskets, PS4S tires) and made $34,000 — up from $28,000 on Cars and Bids under a year earlier. Four44 flagged the flip; the market paid the service bill anyway.
Incomplete service history / undocumented ownership periods discount -10% or so, per commenter estimate
On the 20k-mile arctic silver S, NHS1 questioned ten years of undocumented ownership and no fluid records; Bavarianchops estimated the car would have made $40k with records and correct wheels rather than $36,000.
Non-original oversized wheels/tires discount unclear, bundled into the ~$4k penalty above
Dan_in_Reno on the arctic silver S: 20" Champion wheels with 245 front/305 rear are "likely heavier and also that's too much rear tire for a stock cayman... It will push badly." The seller pushed back, which read poorly in-thread.
Mileage on early base/S cars premium weak — roughly +$6k from 71k to 20k miles
20,000 mi → $36,000; 64,000 mi → $34,000; 71,000 mi → $30,000. That is a shallow curve. Do not overpay for a garage queen early S; the $2,000 gap between 20k and 64k miles is inside noise.
Mileage on the R premium +$10k for 15k vs 38k miles
$79,618 for the 15k-mile Platinum Silver R against a reported $70k private purchase of a 38k-mile black R. Sample of two — treat as indicative only.
Manual transmission premium unclear from this data
The transmission split in the analysed subset is only n=3 manuals at a $34,000 median, with the sole PDK car being an R at $79,618 — variant swamps gearbox. The R thread's HelpMeHelpU, a self-described "MT guy," argued PDK "fits this car exceptionally well," so PDK is not a penalty on the R. No usable evidence on S cars.
Unusual factory options (Turbo II forged wheels, Sport Chrono Plus, bi-xenons with dynamic cornering, Preferred Package) premium unclear, but consistently cited in the strongest results
andy7777 on the R: "The Turbo II wheels are unusual and almost never seen, they are forged unlike the standard Spyder wheels." All three cars over $34,000 carried bi-xenons and either Sport Chrono or Preferred Package.
Colour combination premium unclear
Midnight Blue over sand beige was repeatedly listed as a strength on the $34,000 car; Arctic Silver and Carrara White over black drew no colour commentary. Thin evidence — treat as a tiebreaker, not a driver.

Known issues
majorCylinder bore scoring on the M97 3.4 (Cayman S, 2006–2008)
raised explicitly on 2 of the 4 cars analysed — both early S cars — and it is the single most-repeated technical question in these threads
Caymangolfer on the Carrara White S: "The 987 S has more bore score concerns than the base so I and I am sure others would like to get some peace of mind on that." Robert_Brown added: "Bidders are going to want to see the exhaust on the cold start video for evidence of bore scoring." On the arctic silver S, shanman5678 asked for oil analysis specifically for bore scoring; the seller claimed clean oil with no metal but produced no lab report or borescope.
Check: Cold-start video with the camera on the exhaust tips (looking for smoke/soot and ticking), a borescope of all six cylinders, an oil filter cut open and inspected for ferrous material, and a Blackstone-style oil analysis. Also log oil consumption over a known interval.
major if it fails, low probability on the larger M97 bearingIMS bearing on 2006 M97 cars — non-serviceable, and sellers say so to close the conversation
raised on 1 of 4, but it is the standing question on every pre-2009 987
fly_guy asked whether the IMS bearing had been addressed and bore scoring documented on the arctic silver S. The seller replied that 2006 models have a non-serviceable M97 IMS bearing and that independent shops told him it is not a concern. That is the conventional view and is probably right, but it was asserted rather than evidenced — no PPI, no borescope.
Check: Confirm the engine is the 2006-on M97 with the larger bearing; pull the oil filter and magnetic sump plug for debris; ask for any prior clutch job invoice (the only realistic time anyone would have looked). A 2009+ DFI 9A1 car sidesteps this issue entirely.
moderateWater pump, air-oil separator, thermostat and intake manifold gaskets as a service cluster
documented as replaced on 2 of 4 cars; the third had a major service in Nov 2024
The $34,000 midnight blue S had water pump, drive belt, AOS, thermostat and intake manifold gaskets all replaced in one November 2025 visit; the $36,000 arctic silver car had its water pump done in March 2020. These are consumables on this platform, not surprises.
Check: Dated invoices for water pump and AOS. If neither has been done in the last five years or 40k miles, budget ~$5–6k — that is what the midnight blue S's November 2025 bill covered.
minor to moderate depending on rangeOverrev events in the DME report
1 of 4 cars, but a DME report was requested on 3 of 4 and only supplied on one
Spokayman on the midnight blue S: "The overrev report is overall not too bad on this car... even Porsche will allow some of that in their CPO cars," and on the worst readings, "when only 1 is recorded it is an (electrical?) anomaly and not actually real. It also occurred many hundreds of hours ago, at hour 812 of 1643 total hours." Useful expert-sounding read, but it is one commenter, and the most recent Range 1–2 event was only 19 engine hours before sale.
Check: Pull the DME/overrev report at PPI. Ranges 1–2 are common and largely benign; Ranges 4–6 with multiple ignition counts are the ones that end negotiations. Cross-reference the engine-hour timestamp against total hours.
moderateSellers declining to provide paint-meter readings
2 of 4 cars — requested and not supplied on the Cayman R, and simply not offered on two others
beamerdan1 requested paint readings on the $79,618 Cayman R three hours before close; the seller asserted no paintwork but never supplied numbers. By contrast, the midnight blue S published meter readings confirming all-original OE paint — and it beat a car with 44,000 fewer miles by only $2,000 less.
Check: Take your own paint depth readings at PPI on every panel including the roof and door bottoms. Carfax-clean means nothing about respray history on a 15–20 year old car.
minorHeadliner sag and interior heat damage
called out as a specific strength on 2 of 4 cars, which implies it is a known failure
The Florida-kept Cayman R's listing highlighted "Perfect headliner condition (critical for FL heat exposure)" and the arctic silver S was described as having "no headliner or door panel issues." Sellers only advertise the absence of a problem that buyers expect.
Check: Press the headliner at the A-pillar and rear edges; check door card sail panels and the dash top for lifting adhesive, especially on Sun Belt cars.
minorRattles and trim noise over rough surfaces
1 of 4
DanZZZ on the Carrara White S noted the driving video showed "potholes galore with stuff shaking and rattling all over the place." One observation from a video, not an inspection — verify yourself.
Check: Drive it over broken pavement, not just smooth road. Check the rear hatch struts, targa-style roof seals on Cayman, and interior trim clips.
minor but expensiveSingle key supplied
1 of 4
The midnight blue S seller: "We currently only have one key. We'd be more than happy to provide a second one at our dealer cost."
Check: Confirm two working keys with fobs before bidding; a replacement programmed key on this generation is a several-hundred-dollar item and signals a thinner history file.
Pre-purchase checklist
Decide the variant first: base 2.7/2.9, S 3.4, or R/Black Edition/S Sport. The R is a $70k+ car with its own buyer pool; nothing you do to an S makes it a substitute.
If you want to remove the two big engine questions entirely, buy a 2009+ 987.2 with the DFI 9A1 engine — no IMS bearing, materially fewer bore-scoring reports. That decision is worth more than any inspection on a 2006–2008 car.
On any 2006–2008 S: insist on a borescope of all six cylinders plus an oil filter cut and lab oil analysis before you bid. Two of the four recent threads had bore-scoring questions that sellers answered with words rather than data.
Demand a cold-start video shot from behind the car with the exhaust in frame — Robert_Brown's exact prescription in the Carrara White thread. Listen for cold ticking and watch for blue/grey haze and soot patterning.
Pull the DME overrev report. Look at Ranges 4–6, the ignition count per event, and the engine hour at which they occurred relative to total hours.
Take paint-depth readings on every panel yourself. The midnight blue S published meter readings and it showed in the result; the Cayman R seller refused and still made $79,618, but you are not obliged to take that risk.
Verify water pump, AOS, thermostat and coolant hose service within the last five years. Absent invoices, deduct $5,000–6,000 — that is precisely the bill the midnight blue S carried, and it moved the price by about that much.
Check the wheels are the correct factory size and offset. Oversized aftermarket setups are a documented cash penalty on this model, not a taste question.
Press the headliner and inspect door-card sail panels, particularly on cars from hot states.
Drive it over deliberately rough pavement and listen for interior rattles and suspension knock; check the rear hatch and struts.
Confirm two keys, the original window sticker, both owner's manual sets and the tool kit. All three of the stronger results here had at least the window sticker.
Check tire date codes. PS4S on all three strong cars, but the arctic silver S's August 2023 tires had covered under 175 miles — old rubber on a low-mile car is a replacement cost, not a selling point.
Ask the seller
Has the engine been borescoped, and can you send the images and the cylinder-by-cylinder notes? If not, will you allow it at my cost before the auction ends?
Do you have a lab oil analysis (Blackstone or equivalent) from the current oil, and can you cut the current filter open and photograph the media?
Can you pull and post the full DME overrev report, including all six ranges with ignition counts and engine hours?
When were the water pump, air-oil separator, thermostat and coolant hoses last replaced, and do you have the invoices?
Has the clutch or RMS ever been out, and if so did the shop look at or replace the IMS bearing while it was in there?
Can you provide paint-meter readings for every panel, including the roof and lower door skins?
Are the wheels the factory size and offset, and do the original wheels come with the car?
How many keys, and do you have the original window sticker and complete book set?
What does the 'decline' notation in the dealer service records refer to — which items were declined and when? (This exact vagueness went unexplained on the $79,618 Cayman R.)
When did you buy the car, what did you pay, and where? A car that traded elsewhere within the last 12 months is a flip and you should know what the previous number was — Four44 caught exactly that on the midnight blue S ($28,000 on Cars and Bids, $34,000 on BaT less than a year later).
Any gaps in the ownership chain, and can you produce service records covering them?
Walk away when
Bore-scoring or IMS questions answered with 'my shop says it's fine' rather than a borescope image, a filter cut or a lab report. This happened on the $36,000 arctic silver S and it is the most common evasion in these threads.
No pre-purchase inspection performed by the current owner when they bought the car — the arctic silver S seller confirmed he bought a ten-year-old 987 in 2016 with no PPI at all, and then couldn't answer a decade's worth of questions.
Paint-meter readings requested and not provided. It happened on the Cayman R late in the auction; a seller confident in original paint takes the readings.
Very low mileage plus no service records. 'Kept to preserve mileage' with ~2,000 miles in ten years and no contemporaneous invoices is a storage story, not a maintenance story — and storage brings its own problems on these cars.
Recent trade history at a materially lower price. The midnight blue S changed hands at $28,000 on Cars and Bids and reappeared at $34,000 with a $6,000 service invoice. That one is defensible; a flip without the invoices is not.
Oversized aftermarket wheels with mismatched staggered tires, especially where the seller argues with knowledgeable commenters about the handling consequences rather than acknowledging the mod.
One key and no window sticker or books — a proxy for a thin file generally.
A Cayman R optioned away from its purpose (heated sport seats instead of the lightweight buckets, per the $79,618 car) — buyers noticed, and it is a rational reason to bid a collector R lower.
Budget
Base 987 Cayman, driver-grade with 70–100k miles and honest wear: roughly $18,000–25,000, i.e. at or below the 25th percentile of $25,000. Cayman S, sorted, documented, under 80k miles, correct wheels, water pump and AOS done: $30,000–36,000 — the three most recent S sales landed at exactly $30,000, $34,000 and $36,000. A genuinely best-in-class early S with full records, original paint verified by meter, borescope evidence and sub-40k miles should be a $38,000–42,000 car; Bavarianchops thought $40,000 was on the table for the arctic silver example had it kept its original wheels and a complete file. A 2009+ 987.2 S with DFI carries a premium over the 987.1 and sits comfortably in the upper half of the $25,000–39,000 interquartile band and above. Cayman R: budget $70,000 minimum for a 30–40k-mile example, $78,000–85,000 for a low-mile, well-optioned, two-owner car, and expect the very best cars to press toward the $100,000 print the model set in 2026. Whatever band you're in, hold back $5,000–6,000 for the water pump/AOS/thermostat/belt service if it isn't documented.
2.2x the concurrent Cayman S results and roughly 2.4x the all-time median of $30,987. Not really an outlier so much as a different market: 15,000 miles, two owners, rare Turbo II forged wheels, Sport Chrono Plus, and bidding that ran to within $7,000 of the original $86,675 MSRP. A commenter reported paying $70k for a 38k-mile R, which puts this result inside the R band rather than above it. It does show what the top of the 987 market now looks like, consistent with 2026's $100,000 ceiling.
A $6,000 gain on a car that had traded at $28,000 on Cars and Bids less than twelve months earlier, after roughly $6,000 of documented service. The market paid the invoice back essentially at par — proof that on early S cars, receipts are worth more than odometer readings. It landed only $2,000 below a 20,000-mile car with a thin history file.
The softest of the three recent S results, and the reason is instructive: no-reserve format, no DME report available despite a buyer request, and a seller who only supplied the exhaust-focused cold-start video after being pressed on bore scoring. Excellent single-owner history and a comprehensive November 2024 Kelly Moss service still only got it to the 2026 median.
Verdict
The 987 is the sweet spot for a driver who wants mid-engine Porsche balance without Cayman GT4 money — BlitzLead's line in the Carrara White thread, "one of the best handling production Porsches ever built without the massive purchase price," is exactly why 87.2% of these sell. But the cheap-Porsche era is closing: the trailing-12-month median is $33,250, up 18.8%, and 2026 is running a $36,000 median. Buy a 2009+ 987.2 if you want to sleep at night and can stretch; buy a 2006–2008 S only with a borescope, an oil analysis and a DME report in hand, and pay $30–36k for one with receipts rather than $36k for one with low miles and no paperwork. The R is a separate, firm, $70k-plus collector market — buy it for the aluminium doors, bespoke suspension and rarity, not as an upgraded S, and don't be scared off by PDK.
The statistical base is strong — 666 completed auctions over ten years — but the deep-analysed sample is only four cars, three of which are 2006 Cayman S manuals sold within a two-week window in July 2026. That means: (1) I have essentially no listing-level evidence on base 2.7/2.9 cars, on any 987.2 DFI car (2009–2012), on Black Edition or S Sport, or on PDK versus manual within the same variant — the transmission median shown ($34,000 manual, n=3) is statistically meaningless; (2) the mileage-versus-price table has four data points, one of which is a different model, so treat the 'shallow mileage curve' finding as indicative of early S cars only; (3) the R conclusions rest on one auction plus one commenter's anecdote about a private $70k purchase. All comment-thread material — Spokayman on overrev ranges, Dan_in_Reno on tire sizing, Bavarianchops' $40k estimate — is unverified opinion from strangers, though the bore-scoring and IMS concerns recur consistently enough, and align well enough with what specialists say about M96/M97 engines generally, to be treated as real. Finally, the year-by-year medians mix variants, so the 2026 jump to $36,000 may partly reflect more R/limited cars coming to market rather than pure appreciation on ordinary examples.
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
Jul 24, 2026 · 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
A garage-kept, low-mileage Cayman R with excellent provenance and rare Turbo II wheels that sold at fair market price in competitive bidding, though the late-stage paint meter request went unresolved and the car sacrifices some weight-saving authenticity with sport seats instead of carbon buckets.
Paint meter readings requested late in auction but not provided despite seller assurance of no paintwork · Vague reference to 'decline' in service records not explained by seller
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
