A one-year-only manual Turbo S market that has just re-rated hard — median sold price jumped from $71,500 to $94,000 in twelve months — but the money is now concentrated in coupes, sub-20k-mile cars and 1-of-1 colours, while ordinary 40k-mile black cabriolets still trade in the $70s.

The market

Across all 103 completed BaT auctions for the 2005-onwards 6-speed 996 Turbo/Turbo S, 71 sold (68.9% sell-through) at a median of $75,000 and a mean of $87,457 — the gap between those two numbers tells you the shape of this market: a broad mass of cars in the $60k–$93k band (25th percentile $64,500, 75th percentile $92,998) with a thin, very expensive tail running to $409,996. Every analysed car is a manual (median $77,500, n=40), so the transmission is not a variable here — it is the entry ticket.

The trend has broken upward. Last-12-months median is $94,000 against $71,500 the year before, +31.5%. By calendar year the path was $85,250 (2021), $93,499 (2022), $84,996 (2023), a genuine trough at $71,500 (2024), $75,000 (2025), and then $158,500 for 2026 (n=7, $84,100–$409,996). Treat the 2026 figure with care — it is inflated by 222-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed at $409,996, 1,100-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed at $199,000 and Viola Metallic 2005 Porsche 911 Turbo S Cabriolet 6-Speed at $168,000 — but the mid-market moved too: 44k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed made $94,000 in May 2026 with a disclosed 2014 accident, where a comparable 44k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed sold for $65,000 in October 2023 and another for $70,000 in March 2024.

The spread between good and bad is roughly 2:1 within the same mileage band, and it is driven by body style, colour, originality and documentation rather than condition alone. Mainstream colours cluster tightly: GT Silver Metallic $78,996 (n=7), Black $71,500 (n=8), Arctic Silver Metallic $70,000 (n=13). Coupes carry a clear premium over cabriolets at like mileage — No Reserve: 19k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed brought $120,000 while 19k-Mile 2005 Porsche 911 Turbo Cabriolet 6-Speed brought $84,100, and No Reserve: 46k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed made $78,000 against $60,500 for 46k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed.

Sell-through behaviour is the most useful signal in the file: 32 of 103 auctions ended reserve-not-met, and the RNMs are overwhelmingly the low-mileage, seller-hyped cars, not the tired ones. 2,700-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed drew $227,500 and still failed; the same car relisted as 2,800-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed with a reserve cut from $275k and stalled at $150,000. 989-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed stopped at $120,000, 9k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed at $125,000, 4,900-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed at $102,000, and 37k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed at $96,000 as recently as August 2026 — prompting bmdaia's line, "When a black convertible doesn't make reserve at over $100K you know the Mezger market has seismically shifted." No-reserve cars, by contrast, clear reliably and sometimes cheaply: No Reserve: 2005 Porsche 911 Turbo S Cabriolet 6-Speed at $47,500 and $57,000, No Reserve: 13k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed at $85,000. If you are buying, the reserve-not-met cars are your negotiating pool; if you are bidding, the no-reserve cabriolets are where the value has repeatedly been left on the table.

What moves the price

Sub-5,000-mile "time capsule" preservation premium +150% to +400% over a 40k-mile car

222-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed sold for $409,996 against a $75,000 model median; 1,100-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed took $199,000, with bmdaia commenting "Stolen for sure!"; No Reserve: 7k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed brought $140,000. The premium is real but reserve discipline matters — 989-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed and 4,900-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed both failed to sell at $120,000 and $102,000 respectively.

RecoveringAtty summarised it on the 9k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed thread: "The cab market is soft… most of the bidding is below 2021-22 levels."

Viola Metallic 2005 Porsche 911 Turbo S Cabriolet 6-Speed sold for $168,000 at 21,000 miles after registry-keeper c041v confirmed "I know of no other Viola Metallic example out there… for the entire 996 Turbo run, the PTS option had well under a 1% take rate." 38k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed in Speed Yellow over Metropol Blue made $158,500 — roughly double what GT Silver and Arctic Silver cabs of similar mileage bring. Arena Red Metallic 2005 Porsche 911 Turbo S Coupe 6-Speed took $100,997 back in November 2022 despite a 2014 accident and resprayed rear bumper, on the strength of being the only PTS Arena Red example globally.

Modified 2005 Porsche 911 Turbo S Cabriolet 6-Speed with a genuine 2006 RUF RTurbo S 550hp conversion failed to sell at $71,500 — commenters wanted written RUF documentation that never appeared. 37k-Mile Modified 2005 Porsche 911 Turbo S Cabriolet 6-Speed with $44k of BBi/Haydon Bros work and a 475whp dyno sold for only $71,500, with pkalber asking "Confused with all of the upgrades and tune, yet only gaining 30 HP?" No Reserve: 48k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed (EVOMS-built, GT Silver over Boxster Red) sold at $93,000 — Pirahna noted it "Sold for the exact same price it sold for 1.5 years ago," flat over 18 months while stock cars appreciated.

23k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed with a $11k front-corner repair at an authorised shop sold $73,000 — Cheflife1979: "Did somebody really just get this for 30k below market." 31k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed with a documented 2011 rear-end hit and a right front fender reading 09/08 mils still made $92,996 because Chris_F published every panel reading and the full police report.

26k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed failed at $59,000 with steel rotors fitted and the factory PCCBs gone; TheRealDOh: "This amazing model would go for more but it is missing the carbon brakes, that's a 5 figure part. There's your price gap right there." Conversely 23k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed earned praise for the seller sourcing a matching hardtop and mounts. 46k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed came with one key and the dealer refused to order a second — it sold at the bottom of the band, $60,500.

Documentation package: DME/over-rev report, paint-meter sweep, continuous service records premium +5-15%, and it is the difference between selling and RNM

No Reserve: 2005 Porsche 911 Turbo S Coupe 6-Speed with a $37,000 September 2024 service file and pinned coolant lines took $96,000, with bmdaia calling it "the most well maintained and documented Porsche I've ever seen in over 30-yrs." 31k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed published full-car paint readings and a clean DME and made $92,996 despite an accident.

Non-S 2005 Turbo (415hp, no PCCB, no X50) discount -15-25% vs a Turbo S at comparable mileage, but rarity partly offsets

No Reserve: 47k-Mile 2005 Porsche 911 Turbo 6-Speed, argued by bmdaia and previous owner Lunatic_Fringe to be the only GT Silver 996 Turbo imported to the USA, made $69,996 — inside the Turbo S band. But 42k-Mile 2005 Porsche 911 Turbo Cabriolet 6-Speed in 1-of-1 Carmon Red failed at $45,000 with PorscheTeam protesting "This is a $70k vehicle," and Original-Owner 2005 Porsche 911 Turbo Cabriolet 6-Speed with 12,000 miles failed at $66,500. The non-S buyer pool is thinner and less forgiving.

Known issues

majorOriginal coolant pipes glued rather than pinned or welded — failure requires engine-out to fix properly

raised or flagged on at least 12 of the 60 cars reviewed; the single most persistent technical thread in the file

On 37k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed, Turbopowered_gsr wrote "They have not – it's not explicitly stated, best to assume no. Therefore engine out required later (not immediate)" — the car then failed at $96,000. On 44k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed the seller confirmed no record of pipes ever being pinned. On 2005 Porsche 911 Turbo S Coupe 6-Speed (77k, Seal Grey) the seller — himself a Porsche mechanic — "never saw the need to do it." Counterweight: on 31k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed, MEZGER917 said they had sold numerous 996/997 turbos and seen exactly one pipe failure at 100k miles, and boba911 cited a friend's X50 at 685k miles on original pipes; @Kingturbo, however, reported a temp spike from 180°F to redline at ~100 mph from a line failure. Cars that have had it done — No Reserve: 2005 Porsche 911 Turbo S Coupe 6-Speed (pinned 2022 and 2024) and 48k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed (welded) — sold at $96,000 and $67,000 respectively with the topic closed early.

Check: Get the car on a lift and photograph the pipe junctions; demand the invoice naming the shop and the pinning/welding method. If it is not on paper, budget $3,000–$6,000 with engine drop and assume you own the risk.

37k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed had cylinders rebuilt May 2026; 2005 Porsche 911 Turbo S Cabriolet 6-Speed (70k, black) had top hydraulics, cables and potentiometer plus headliner replaced July 2022; 44k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed had cylinders and hoses replaced June 2025; 46k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed had rams repaired June 2023; No Reserve: 2005 Porsche 911 Turbo S Cabriolet 6-Speed had cylinders replaced; 2005 Porsche 911 Turbo S Cabriolet 6-Speed (40k, GT Silver) had them rebuilt in 2017. On 23k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed commenter DrmKlr, himself a 996 TT owner, called the top's B-pillar creasing "inevitable design flaws."

Check: Cycle the roof three times cold and watch for weeping at the cylinders and hesitation mid-cycle; check the boot carpet and rear seat bases for hydraulic fluid or water staining; ask for the cylinder rebuild invoice and date.

raised or repaired on 5 of 60 cars reviewed

23k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed arrived at auction with the spoiler inoperative — service notes showed broken limit switches on the hydraulic piston, to be replaced before handover. 44k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed had the spoiler motor replaced March 2024. No Reserve: 2005 Porsche 911 Turbo S Coupe 6-Speed had the hydraulic spoiler drive unit replaced March 2022, and 4,900-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed needed a spoiler wiring harness in August 2022 at under 5,000 miles. thefleshrocket, commenting on 38k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed, grouped "the spoiler hydraulics having been addressed" with coolant lines and radiators as "not-insignificant expenses."

Check: Cycle the spoiler manually and at speed, check for stored codes, and confirm both limit switches operate — a dead spoiler is a known symptom, not a quirk.

moderateHVAC blend-door / evaporator foam disintegration — black foam debris blown out of the vents

raised on 5 of 60 cars; described by owners as universal to the generation

On 44k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed the seller admitted "small specs of foam occasionally emerge from vents when heat or AC are blasted" and had not addressed it. On Original-Owner 2005 Porsche 911 Turbo Cabriolet 6-Speed, DrmKlr stated flatly that blend-door foam breakdown "will eventually happen to every 996," correcting RPFL's assumption that the black dust came from ductwork. No Reserve: 2005 Porsche 911 Turbo S Cabriolet 6-Speed (81k) — seller expected "like everyone of them to have older foam which will break down." On 31k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed, Chris_F confirmed no service record showed the repair had been done and Hurtig described a vacuum-based fix.

Check: Run the blower on max heat and max A/C with a white cloth over the centre vents and look for black particles; ask whether the blend-door foam or heater box has ever been opened.

Check: Feel for a soft or sinking pedal and a high/vague take-up point; ask directly for the clutch accumulator and slave cylinder replacement dates and the mileage at which the clutch pack was last renewed.

majorPCCB rotor life cannot be judged from photos or a caliper, and replacement is catastrophic in cost

raised on 4 of 60 cars; replacement quoted at $35k in one thread, "5 figure part" in another

On 2005 Porsche 911 Turbo S Cabriolet 6-Speed (Guards Red, 66k) thefleshrocket demolished the seller's approach: "carbon ceramic brake rotor wear doesn't show up as reduced thickness, it shows up as lower weight. The only way to accurately know if CCB rotors are worn is to remove them, clean them, weigh them." On 31k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed the seller admitted "The PCCB have not been weighed. Condition of rotors look and feel to be good." On 40k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed commenters put PCCB replacement at $35k with no measurements offered since 2016. 26k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed had lost its PCCB rotors entirely and failed at $59,000. Contrary voices exist — bmdaia claims 100k-mile life — but the cost asymmetry favours measurement.

Check: Have the rotors removed, cleaned and weighed against factory spec — thickness measurement is meaningless. Confirm the discs are genuine PCCB and present at all.

moderateRetroactive and phantom Carfax damage entries

35k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed was bought in 2023 with a clean Carfax and a 2019 "minor damage" entry later appeared, while AutoCheck showed zero accidents. 2005 Porsche 911 Turbo S Cabriolet 6-Speed (91k, Arctic Silver) had a May 2018 entry surface a year after purchase and the seller opened a dispute. 38k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed's seller said the damage "wasn't there when we bought the car and mysteriously just popped up again." On No Reserve: 47k-Mile 2005 Porsche 911 Turbo 6-Speed, Clawdog wrote that Carfax "said they didn't know how it came to be, but it was there."

Check: Pull both Carfax and AutoCheck yourself, then verify with a full-car paint-meter sweep rather than arguing about the report. Bumper covers and mirrors are routinely resprayed and are not the issue; quarter panels, hoods and doors are.

moderateAge-related chassis and cooling consumables: motor mounts, front axle/CV joints, water pump, radiators, ignition coils, taillight mounting tabs

appears across the majority of the more thoroughly serviced cars — these are not defects so much as a bill that has either been paid or is coming

2005 Porsche 911 Turbo S Cabriolet 6-Speed (70k) had a July 2025 $19,000 reconditioning covering plugs, coils, belts, motor mounts, struts, sway bar links and HVAC blower. 44k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed had front axle shafts rebuilt for "time-related CV joint degradation," water pump, mounts and transaxle mount in December 2023 — roughly $30k over three years. On 31k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed, saxonthebeach read sagging exhaust tips as degraded motor mounts. On 26k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed the seller confirmed "996 turbo coils cracking is a fairly common thing," and on 48k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed @MatteeeB found the near-universal cracked taillight bolt tabs, fixed with ~$125 "lightsavers."

Check: Look for a recent bundle covering motor and transaxle mounts, water pump, drive belt, coils, plugs and front axle shafts. Absence of that bundle on a 20-year-old car is a $8k–$15k deferred liability, not a bargain.

raised on 5 of the low-mileage cars reviewed

On 222-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed the original 2005 Bridgestones are still fitted and described as "museum-level"; the seller volunteered that the tank was "regularly cycled with fresh gas." On 9k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed, Ex36 rejected the seller's cosmoline explanation outright: "the mufflers in Pic 104 say it all. They're brown, and that sure ain't Cosmoline" — the car failed at $87,000. On Original-Owner 2005 Porsche 911 Turbo Cabriolet 6-Speed, Oliverjunior wrote "12k miles? and texas car? very odd, undercarriage & engine look like 120k miles on cars from back east driven mostly on snow and salt!" — RNM at $66,500. On 12k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed, Always108 flagged 2014-date tyres as an immediate $2–3k cost.

Check: Read DOT date codes on all four tyres and price a replacement set into your bid; inspect fasteners, mufflers and suspension hardware under the car in person; ask when the fuel was last cycled and whether the car has been on a tender.

minorNon-issues the market keeps mistaking for red flags — missing under-hood option sticker, and IMS bearing anxiety

argued on at least 8 of 60 listings, always resolved the same way

autobonrun, a 2005 Turbo S owner, on 11k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed: "In the mid 2000's Porsche became totally inconsistent in applying the option sticker… they did not issue a similar bulletin announcing when they stopped applying them." MKT corroborated on 2005 Porsche 911 Turbo S Cabriolet 6-Speed (40k GT Silver): "Most Turbo S' do not have the hood sticker." On IMS, bmdaia quoting Porsche Motorsport on 2005 Porsche 911 Turbo S Cabriolet 6-Speed (91k): "The oil-fed journal-type IMSB in the Mezger is as indestructible and immortal as the endurance racing Mezger engine itself," and DrmKlr confirmed the same on 23k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed. Treat a seller who cannot answer the IMS question correctly as a seller who does not know the car.

Check: Do not discount a car for a missing hood sticker; check the copy in the owner's manual or decode the VIN instead. Do not pay for, or ask about, IMS work — the Mezger's oil-fed journal bearing is a different architecture.

majorSuspect engine work on a supposedly bulletproof engine

one clear case in 60, but a severe one

2005 Porsche 911 Turbo S Coupe 6-Speed (77k, Seal Grey) carried an August 2020 $15k dealer rebuild whose invoice blamed a stretched timing chain. bmdaia: "Stretched timing chain on a Mezger is unheard of (you could tow a locomotive with the Mezger's timing chain)." The consigning dealer's own position was that the fault "was misdiagnosed." No DME report was provided despite the recent major engine work; the car sold for $78,500, which is unremarkable money for a manual Turbo S coupe at that mileage.

Check: If an engine has been opened, get the full invoice, the failed-part diagnosis and a compression/leakdown plus borescope. A "stretched timing chain" claim on a Mezger should be treated as an unexplained rebuild until proven otherwise.

Pre-purchase checklist

Ask the seller

  1. Have the coolant pipes been pinned or welded, by whom, at what mileage — and can you send the invoice?
  2. When were the PCCB rotors last weighed, and what was the result against factory weight?
  3. Can you produce a Durametric or PIWIS DME report showing over-rev ranges and stored faults, dated within the last month?
  4. What are the paint-meter readings on each quarter panel, the hood and the roof — and can you photograph the gauge on each?
  5. On a cabriolet: when were the top's hydraulic cylinders, hoses and potentiometer last replaced, and has the headliner ever been out?
  6. When were the motor mounts, water pump, drive belt, ignition coils, plugs and front axle shafts last done? If none of them, why not on a twenty-year-old car?
  7. Has the ECU ever been tuned, and if so, is there a handheld unit to revert it? (Several sellers in this set denied a tune until the bolt-on evidence forced them to admit one.)
  8. Are the factory wheels, original exhaust, hardtop, tool kit and both keys included?
  9. How many owners does the title chain actually show, and can you explain each Carfax owner entry?
  10. Are there any "towed" or "won't start" entries anywhere in the service file? One bidder walked away from a fully reconditioned car purely on those two phrases.
  11. If the car is modified by a named tuner (RUF, EVOMS, BBi): where is the original conversion paperwork? Verbal authentication has repeatedly killed bids on this model.

Walk away when

Budget

Driver-grade, today: $55,000–$72,000 buys a cabriolet with 70k–100k miles, a soft top that has already needed hydraulics, unpinned coolant pipes and a patchy record — see No Reserve: 2005 Porsche 911 Turbo S Cabriolet 6-Speed at $57,000 (92k) and 2005 Porsche 911 Turbo S Cabriolet 6-Speed at $51,000 (91k). Budget $10k–$15k on top for the deferred bundle: coolant pipes, motor mounts, water pump, coils, top hydraulics, tyres.

Strong example: $85,000–$100,000. That is where a 30k–50k-mile Turbo S cabriolet with a real service file and disclosed, documented paint now trades — 44k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed at $94,000 (May 2026), 39k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed at $91,000, No Reserve: 48k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed at $93,000. For a coupe, the same money is closer to entry-level: No Reserve: 2005 Porsche 911 Turbo S Coupe 6-Speed at $96,000 with 59k miles and a $37k service history is arguably the single best-value car in the whole file.

Best-in-class driver: $100,000–$140,000. Sub-35k-mile coupes with the Aerokit and clean documentation — 31k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed at $108,000, No Reserve: 19k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed at $120,000, No Reserve: 7k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed at $140,000. Expect to be outbid below $100k for a genuinely unmolested low-mile coupe in 2026.

Collector/trophy tier: $155,000 to over $400,000, and it is bought with colour and odometer, not condition. Paint-to-sample or 1-of-1 factory colours run $158k–$168k; four-figure-mileage cars run $199k upward; the 222-mile coupe was a $409,996 one-off. Below roughly $150k, spec buys you nothing extra — above it, spec is the only thing you are buying.

Outliers

222-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed

222-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed $409,996

5.5x the all-time model median. Almost certainly the lowest-mileage 996 Turbo S in existence, in 1-of-17 Slate Grey, previously sold by the winning dealer in 2021 at 196 miles. It is a mileage trophy, not a car — 26 miles added in four years, original 2005 tyres, no driving video, and the title legend reads "Mileage Not Required." Not a comparable for anything you would drive.

1,100-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed

1,100-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed $199,000

Highest cabriolet result recorded. Sold in August 2026 despite the initial listing being withdrawn for AI-edited photographs and the seller's team using ChatGPT to write comments. That a transparency scandal cost nothing tells you how much the market is paying for a four-figure-mileage manual Turbo S cab.

Viola Metallic 2005 Porsche 911 Turbo S Cabriolet 6-Speed

Viola Metallic 2005 Porsche 911 Turbo S Cabriolet 6-Speed $168,000

Sold for roughly double the $78,996 that 35k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed brought four months earlier, despite a phantom Carfax damage entry, a repainted front bumper and mirror, six-year-old tyres and no mention of coolant lines, radiators or spoiler hydraulics.

2005 Porsche 911 Turbo Cabriolet 6-Speed

2005 Porsche 911 Turbo Cabriolet 6-Speed $45,750

The floor of the entire dataset. Non-S 415hp car, 79,000 miles, aftermarket taillights, undocumented 2021 service claims and no DME report — the exact combination the market punishes. Note this is the last non-S Turbo Cabriolet built for North America per c041v's VIN work, and rarity bought it nothing.

No Reserve: 2005 Porsche 911 Turbo S Cabriolet 6-Speed

No Reserve: 2005 Porsche 911 Turbo S Cabriolet 6-Speed $47,500

81,000 miles, a 2011 rear-impact Carfax entry the dealer could not explain, unpinned coolant lines, no service records and a bent exhaust tip — at no reserve it found $47,500. krowfl's post-mortem: "I think this was a perfect price considering the accident (even though minor) and the miles."

26k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed

26k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed $59,000

Failed to sell at $59,000 with 26,000 miles — an outlier low for the mileage. The factory PCCB rotors were missing (steel conversion fitted), the instrument cluster had been swapped from km to mph, five prior owners, and the car had been on BaT four times in five years.

2,700-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed

2,700-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed $227,500

The most instructive failure in the set: $227,500 bid in May 2023 and rejected against a reserve reportedly around $275k, then the same car relisted as 2,800-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed and stalling at $150,000 three months later. NorCalTurbo called it: "Might be a $1M car in 30 years but today it's a $200k car at best."

Verdict

This is now a two-tier market and you should decide which tier you are in before you bid. If you want the car — the last manual Mezger Turbo, and by consensus of the owners in these threads a better drive than a 992 — buy a documented 30k–60k-mile coupe at $95k–$120k, or accept the cabriolet discount and take a well-serviced 40k-mile cab at $85k–$95k, or a 70k–90k-mile one at $55k–$70k with $15k set aside for pipes, mounts and roof hydraulics. Insist on a weighed set of PCCBs, a real DME report and a full paint sweep; those three documents are worth more than any rarity spreadsheet. If you want the asset, you are competing for four or five cars a year — 1-of-1 colours and four-figure odometers — at $160k–$400k, and the RNM record shows the sellers of those cars are as likely to overreach as to underprice. What I would not buy at these levels: a modified car without the tuner's paperwork, an ultra-low-mileage car with a corroded underside, or anything where the seller shouts about rarity and cannot tell you whether the coolant pipes are pinned.

Several caveats. First, the transmission breakdown is meaningless here — this model definition is manual-only, so the "$77,500 manual median" is just the analysed-subset median, not evidence of a manual premium. Second, the colour medians (GT Silver n=7, Black n=8, Arctic Silver n=13) pool sales from 2018 to 2026 and therefore mix the +31.5% recent re-rating with older, cheaper results; do not read them as a live 2026 price list, and note the statistics explicitly withhold Viola, Speed Yellow, Cobalt Blue, Slate Grey, Seal Grey, Atlas Grey, Guards Red, Basalt Black and Arena Red as too thin — my paint-to-sample premium claim rests on three individual cars, not a distribution. Third, the 2026 median of $158,500 (n=7) is dominated by two extreme outliers; the honest read on the current mid-market is the $84,100–$96,000 band from the ordinary 2026 sales. Fourth, the deep-analysed sample skews heavily toward Turbo S cabriolets; the coupe premium is supported by only a handful of matched pairs, and the non-S 2005 Turbo appears in just five listings, so treat the non-S discount as directional only. Fifth, everything in the "known issues" section comes from BaT comment threads — informed opinion from strangers, occasionally contradicted within the same thread (the coolant-pipe debate cuts both ways; the timing-chain rebuild was disputed by commenters, not by a specialist inspection). I have weighted by recurrence and by whether registry keepers like c041v or repeat owners corroborated, but none of it substitutes for a lift and a scan tool on the specific car you are buying.

Bidding patterns

These are patterns, not findings. A public auction record cannot show intent, and everything below has ordinary explanations — specialists and dealers bid on many cars of one model, enthusiasts run up cars they end up losing, and new accounts are usually just new.

$77,000
· 68,000 mi · manual · black
A well-maintained, low-mileage 996 Turbo S manual coupe with incomplete tune documentation and minor cosmetic work history that sold for notably below comparable market, suggesting either exceptional buyer fortune or reserve calculation miss by seller across three auction attempts.

$70,000
· 44,000 mi · manual · arctic silver metallic
A low-mileage, clean-title 996 Turbo S manual convertible with desirable Mezger provenance, complicated by a failed prior auction, conflicting condition assessments from a motivated viewer versus independent local buyer, and minor cosmetic disputes now resolved at $70k—a solid market price for a future collectible marred by seller reliability questions.
previous auction relisting after winning bidder failed to close in February 2024 · RenoGrant claimed to have viewed car last week and offered $69k, which seller accepted then changed mind; RenoGrant stated cosmetics are weak with scratches, dings, and paint needing detail

$90,500
· 44,000 mi · manual · arctic silver metallic
A genuinely unicorn 2005 manual Turbo S cab with the legendary Mezger engine and solid service history gaps—held solid at $90.5k despite incomplete documentation and no DME report, driven by rarity premium rather than provenance confidence.
Limited service history documentation · No DME/engine analysis report · No service records provided for 11-year gap (2012–2023) prior to current ownership · Seller could not produce work orders for clutch accumulator and water pump service, only inspection photos

Reserve not met
· 68,972 mi · manual · black
A genuinely rare, fastidiously maintained 996 Turbo S manual with unquestionable provenance and legitimate rarity—but vague tune details, Canadian location friction, and a firm reserve against soft final bidding depth left it unsold despite the specification deserving mid-$70k+ interest in a US-based auction.
Aftermarket tune specifics undisclosed · No EPA documentation clarity for US re-import · Reserve not met at $72,500 USD despite extensive seller claims of $20,800 invested since 2021 · Auction location in Canada despite US-spec origin may have suppressed bidding, but seller's reserve strategy unclear
31k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed
$92,996
· 31,435 mi · manual · basalt black metallic
An exceptionally well-documented, low-mileage 996 Turbo S with comprehensive service history and extensive personalization that cleared its accident past through transparent repair records and remains mechanically sound, though the elevated right-fender paint reading and unresolved AC foam defect warrant pre-delivery inspection despite universally positive owner and mechanic endorsements.
April 2011 rear-end accident damage · Paint meter readings on right front fender elevated · April 2011 accident with rear bumper, spoiler, engine lid, and taillight replacement raises concerns about hidden structural or frame damage despite 'minor damage' designation · Right front fender paint meter elevated (09/08 mils) compared to rest of car (03-05 mils), suggesting incomplete or mismatched repair process

No Reserve: 47k-Mile 2005 Porsche 911 Turbo 6-Speed
$69,996
· 47,000 mi · manual · gt silver metallic
A documented unicorn 2005 996 turbo in the only gt silver example shipped to usa, meticulously serviced post-2022 purchase but hampered by mysterious post-sale carfax damage entry and some interior/paint wear that moderately discounted the final gavel price from collectible-rarity expectations.
left door repaint · carfax damage entry appeared after seller's purchase despite seller's claimed thorough inspection and dry-ice detail · conflicting vin database reports: rennlist lists as turbo s while other sources confirm turbo; potential confusion around variant designation
44k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed
$65,000
· 44,000 mi · manual · arctic silver metallic
Exceptionally well-preserved 2005 Turbo S manual cabriolet with full service history and documented low use, though the pristine condition relative to mileage and lack of protection film warrant pre-purchase inspection to rule out storage-only or odometer concerns.
Unusually pristine condition ('looks like 10-15k mile car') paired with 44k miles raises questions about actual usage or previous protective treatments not fully disclosed · Limited transparency on full service history details despite seller claims of 'all services complete'
12k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed
Reserve not met
· 12,000 mi · manual · arctic silver metallic
Exceptionally rare and original 12k-mile 2005 Turbo S Cabriolet with a concerning 2010 oil overfill incident, aging tires, and sparse service documentation that required aggressive transparency demands from knowledgeable commenters to surface credible dealer diagnostics, ultimately failing to meet reserve likely because of Arctic Silver's polarizing appeal and the seller's initial defensiveness undermining collector confidence.
Engine oil overfilled by 5 quarts in September 2010 · Vague initial response from seller regarding the 5-quart oil overfill in 2010 service record; only 1,400 miles added under current ownership suggests car sat unused for extended period after purchase · Limited service history: only two documented service visits (2010 and 2023), despite 12-year ownership; seller claims to have maintained service himself but provides no records
40k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed
$84,996
· 40,000 mi · manual · gt silver metallic
A rare, low-mileage 996 Turbo S with strong service history and exclusive status undermined by concealed prior tuning, paint work on multiple panels following a 2009 accident, unresolved cosmetic issues, and a seller narrative that contradicted documented modifications until pressed.
Prior tuning history concealed initially · Brake pad and rotor status unknown despite mileage · Seller initially denied tune history then reversed course only after detailed technical pushback from experienced commenters · Absence of paint meter data despite admitted respray on multiple panels (front bumper, rear bumper, area behind rear window)
48k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed
Reserve not met
· 48,000 mi · manual · arctic silver metallic
A rare, low-mileage 2005 996 Turbo S manual coupe with impeccable provenance and comprehensive service records that failed to meet reserve at $76k—likely undervalued relative to the $100k+ market established for comparable examples, despite excellent condition and desirable specification.
ECU tune lacks handheld reflash capability · Reserve not met at $76,000, despite strong bidding activity up to that point · Multiple commenters note this price is well below historical market for 996 Turbo S examples (cited as ~$100k range)
2,800-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed
Reserve not met
· 2,800 mi · manual · arctic silver metallic
A spectacularly optioned, nearly museum-piece 2005 996 Turbo S with the legendary Mezger motor and full Turbo S credentials, but market appetite stalled well below the $275k reserve from just three months prior, signaling either seller overvaluation or cooling 996 collector sentiment.
dry-ice blasting on low-mileage example · reserve not met; dropped from $275k reserve (previous auction 08/03/23) to $150k final bid this auction · re-listed within 3 months with significantly reduced reserve expectation
2,700-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed
Reserve not met
· 2,700 mi · manual · arctic silver metallic
A time-capsule final-generation manual-transmission Turbo S with one-of-one factory specification (Aerokit + paint-matched sport seats + carbon interior), pristine at 2,700 miles and expertly presented, that fell just short of reserve despite strong bidding approaching market records—suggesting either aggressive seller expectations or a legitimate collector temporarily out of reach.
Reserve not met despite strong bidding · Reserve set above $227,500 despite multiple expert comments suggesting the car should break records · Seller's reserve strategy may have misjudged market appetite or collector interest
11k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed
Reserve not met
· 11,000 mi · manual · gt silver metallic
An exceptionally preserved, last-of-its-kind manual Turbo S cab with unassailable low mileage and both roof options, but seller's reserve expectations ($120k+) proved disconnected from market clearing price ($102.5k), yielding a failed auction despite enthusiast recognition of its rarity.
Seller initially unresponsive to multiple detailed questions from serious bidders (Campcar noted 'It is hard to be a serious bidder when the Seller provides no answers to legitimate requests') · Reserve not met at $102,500 despite seller's confidence; auction ended without sale on 05/25/2023
9k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed
Reserve not met
· 9,000 mi · manual · speed yellow
A vanishingly rare Speed Yellow 996 Turbo S cabriolet with 9k miles and pristine papers that failed to clear reserve at $87k due to surface corrosion on the undercarriage and a softening collector market, despite being mechanically sound and possessing one of the most desirable color and option combinations ever produced.
Undercarriage corrosion · Undercarriage shows surface corrosion despite only 9k miles, suggesting coastal exposure or storage issues · No authorized Porsche service records in history; only Valvoline and Bradzoil quick-lube entries
31k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed
$108,000
· 31,297 mi · manual · arctic silver metallic
A genuinely rare final-year manual Turbo S with correct aerokit spec and low miles, compromised only by an unnecessary aftermarket exhaust, incomplete service documentation, and unverified motor mount/coolant line condition—but the combination of rarity and driving appeal justified six-figure pricing in a soft market.
motor mounts may be degraded · coolant lines not pinned/welded · Alumni badge initially shown on listing despite seller's claim car was never previously listed on BaT (seller attributed to new BaT software bug) · Misstatements in original description: Sumitomo tires listed when photos clearly show Michelin Pilot Sport 4 S; corrected by BaT after saxonthebeach flag
2005 Porsche 911 Turbo S Cabriolet 6-Speed
Reserve not met
· 89,000 mi · manual · midnight blue metallic
A genuinely rare 996 Turbo S manual cabriolet in desirable color with solid bones, but prior respray, uncertain service history, storage-inflicted paint damage, and advancing mileage (~89k toward eventual rebuild horizon) justified the reserve not being met at $51,500.
Uncertain tune status · Paint overspray/respray evidence · Seller initially uncertain about ECU tune despite X50 kit and 0.9 bar boost; only resolved via indy inspection mid-auction · Missing service history from previous owners; cannot confirm IMS bearing, coolant pipe, or clutch status
26k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed
Reserve not met
· 26,000 mi · manual · seal gray metallic
A well-maintained, low-mileage 996 Turbo S cabriolet hobbled by the deliberate absence of its $5k+ factory ceramic brakes and damaged by four prior BaT listings that signaled market exhaustion and dealer churn rather than cherished ownership.
Missing factory PCCB rotors · Cracked ignition coils replaced · car has been listed on BaT at least 4 times in 5 years, suggesting repeated flipping and possible market saturation fatigue · missing factory PCCB rotors (major value component) with vague explanation; prior owner did not include them, compounded by fact they were located post-2019 auction but missing again
No Reserve: 19k-Mile 2005 Porsche 911 Turbo S Coupe 6-Speed
$120,000
· 19,000 mi · manual · atlas grey metallic
An exceptionally documented, single-owner 19k-mile 2005 996 Turbo S in one of seven known Atlas Grey coupes with full provenance and championship spec (X50, PCCB, manual, AWD) is the final manual Turbo S ever built and a future 7-figure collectible, having sold at a realistic floor price to a serious buyer in a no-reserve format that correctly valued rarity over hype.
No Reserve: 7k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed
$140,000
· 7,000 mi · manual · arctic silver metallic
A genuinely rare 7k-mile 996 Turbo S manual cabriolet with clean history and charity provenance that sold for just over its Gooding price one year later to a serial low-mileage collector, likely destined for rotation rather than regular driving.
old tires on vehicle · window sticker price redacted by Gooding auction house (though seller explained and verified via VIN) · tires from 2005/2007 still on vehicle at 7k miles
No Reserve: 48k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed
$93,000
· 48,000 mi · manual · gt silver metallic
A visually stunning and rare 48k-mile 996 Turbo S in an exceptional color combination, but heavily modified with questionable long-term reliability prospects and missing OEM parts, which sold at $93k—identical to its 2021 price, suggesting mods and recent ignition event erased appreciation upside.
Original factory wheels not with car · Missing original components · Multiple ownership changes in 16 months (sold on BaT Sept 2021, traded to current dealer Sept 2022, now resold Jan 2023) · OEM/factory parts not included with car; history of parts unclear
36k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed
$69,000
· 36,000 mi · manual · gt silver metallic
A genuinely rare, low-mileage 2005 911 Turbo S manual cabriolet with minor cosmetic history (swapped side skirts, replaced front spoiler) and intermittent CD player glitch that sold at $69k—a well-bought example of one of the last analog Turbo S models, never to be repeated in the 911 lineage.
Non-original painted side skirts swapped for carbon fiber adhesive panels (commenter Mercyhealth raised, seller initially evasive, later corrected by chekminc with factory build sheet showing original painted CAY side skirts and CAX front lip were standard; front spoiler shows damage/replacement which suggests prior incident not disclosed in main listing) · Top 2 service records appear to be duplicates (MPH930 observation, seller did not address)
48k-Mile 2005 Porsche 911 Turbo S Cabriolet 6-Speed
$67,000
· 48,000 mi · manual · arctic silver metallic
Pristinely preserved 48k-mile 2005 996 Turbo S manual cabriolet with factory X50 kit and proactive coolant-line work sold for $67k—a rare, well-maintained driver that community consensus deemed significantly undervalued, though delayed documentation and minor cosmetic ambiguities may have suppressed bidding.
Possible paint discrepancy on driver-side front fender and door · Paint color inconsistency in listing · Missing paint meter readings despite multiple requests from experienced commenters (TTownPorsche requested twice, seller promised to obtain but none provided before sale end) · Initial evasiveness about dashboard button functionality
2005 Porsche 911 Turbo S Coupe 6-Speed
$68,996
· 103,000 mi · manual · arctic silver metallic
A comprehensively documented, museum-quality 996 Turbo S manual coupe with factory X50 power, genuine rarity (fewer than 200 examples worldwide), and fastidious collector ownership that commanded $68,996—roughly 50% above typical 996 Turbo money—because the specification and maintenance record proved this 103k-mile example was bought to be preserved and driven right, not flipped.
High mileage (103k) for a 2005 model; commenter 3_pdls notes 'high mileage car' and asks about true driver status · Frequent owner changes indicated by Carfax showing registration history across 7 states (Michigan, North Carolina, Maryland, Massachusetts, Ohio, Pennsylvania, Georgia) over roughly 17 years; commenter Mikado996 sardonically notes 'Reading the CarFax is like watching 8 mid-life crisis happen'

Reserve not met
· 40,000 mi · manual · gt silver metallic
Exceptionally documented and low-mileage Turbo S Cabrio in rare GT Silver with strong provenance and PPI pedigree, marred only by deferred coolant-line service and cosmetic wear, finished unsold at $81k reserve-not-met after late-auction bidding war.

Arena Red Metallic 2005 Porsche 911 Turbo S Coupe 6-Speed
$100,997
· 33,000 mi · manual · arena red metallic
A historically significant 1-of-1 Paint-To-Sample Arena Red final manual Turbo S with 33k careful miles sold for $100,997 to an informed collector—a fair price for a unicorn Mezger despite minor documented paint work and gray interior that some saw as undervaluing an automotive time capsule.
August 2014 accident damage · Minor accident history in 2014 with documented paint work and repaired bumper cover should be verified in person · Multiple paint chips and imperfections on roof and fender that seller acknowledges but characterizes as minor and hard to see - buyer should inspect closely
