Ford GT40 Replica

⚠ 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/ford/gt40-replica/ · 84 completed auctions · 20 read in depth · compiled · 2 versions on file · 5 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. 5 such listings were removed before any figure below was computed — e.g. No Reserve: Ford GT40-Style Neon Sign; No Reserve: Neon Gulf Ford GT40-Style Sign; No Reserve: Ford GT40 Wooden Display Model.

A brand-tier market masquerading as one model: Superformance cars clear $200k–$325k while equally competent ERA, RCR and GTD builds trade at $96k–$157k — and roughly four in ten sellers still can't make their reserve.

The market

Across all 84 completed BaT auctions the median sold price is $140,000 with a mean of $165,757 — the gap tells you the market is skewed by a small group of six-figure-plus Superformance cars. The interquartile range is enormous: $102,500 at the 25th percentile to $228,000 at the 75th, with the full range running $2,500 to $386,000. Sell-through is 60.7% (51 sold, 33 reserve-not-met), which is weak for a modern-collectible category and is the single most important statistic in this report: a third of sellers are asking more than the room will pay. Momentum is mildly positive — last 12 months median $165,000 versus $157,000 the year before, +5.1%.

Do not read the by-year medians as a trend line. 2024 shows $235,500 (n=8), 2025 shows $130,000 (n=10) and 2026 shows $297,500 (n=2). That is mix shift, not a 45% crash and recovery: 2025's sample includes No Reserve: Fiberfab Avenger GT12 Project at $4,100 and One-Owner, Oldsmobile V8–Powered Tornado Sports Cars GT40 Replica at $77,000, while 2026's two sales are both top-tier Superformance cars — Fuel-Injected, Shelby 496 FE-Powered Superformance GT40 Mk I at $325,000 and No Reserve: Roush 427–Powered Superformance GT40 Mk I at $270,000. Once you segment by builder the picture is stable and legible.

The tiers, from the 20 deep-analysed sales: Superformance-bodied cars with Roush 427 or Shelby FE power occupy $200,000–$325,000 (Roush 427IR-Powered Superformance GT40 Mk I at $200,000 post-auction, No Reserve: Roush 427IR-Powered Superformance GT40 Mk I at $229,000, 496-Powered Superformance GT40 MKII 50th Anniversary Edition at $308,500). ERA sits at $130,000–$157,000 with remarkable consistency — 302-Powered ERA GT Mk I $130,000, 351-Powered ERA GT Mk 1 $130,000, 289-Powered ERA GT Mark I $157,000. Race Car Replicas is $107,000–$144,000 (Race Car Replicas RCR40 Mk I sold at $107,000; Race Car Replicas GT40 Mk1 failed at $144,000). GT Developments GTD40 landed $96,500. Owner-engineered one-offs and Superlite-class cars are $67,500–$116,111, mostly unsold. Fiberfab-era 1960s/70s kits are scrap-to-$8k money.

What is actually moving the numbers is not mileage or colour — it is builder reputation, engine provenance, and seller conduct in the comment thread. The correlation is stark: every reserve-not-met car in the deep sample had either an absent seller (Roush 427–Powered Superformance GT40 Mk I, where commenter 1889 wrote "I don't think I've seen an auction where the seller didn't post a single comment," RNM at $201,454) or a build-cost-anchored reserve the market rejected (Godzilla-Powered Superformance GT40 Mk I, $385k claimed investment, RNM at $247,777; 5.2L Aluminator–Powered Superlite GT-R, $152k documented build, RNM at $116,111; 302-Powered Ardern Cars Active Power GT, RNM at $67,500 which commenter jlwdvm noted was "WAY below the price of the kit and parts"). Meanwhile the no-reserve format is doing real work: No Reserve: Roush 427–Powered Superformance GT40 Mk I had already failed to sell on BaT in August 2025 and made $270,000 when relisted with no reserve, and No Reserve: Roush 427IR-Powered Superformance GT40 Mk I ran from a stalled $65,000 first hour to $229,000 in the final hour. Build cost is not a valuation input in this market; the buyer pool discounts labour heavily.

What moves the price

Superformance / licensed-continuation chassis (vs. kit-built) premium +60-120% over ERA/RCR/GTD equivalents

Superformance cars in the deep sample: $200,000, $229,000, $270,000, $308,500, $325,000. Comparable-quality kit builds: Race Car Replicas RCR40 Mk I at $107,000, GT Developments GTD40 at $96,500, 351-Powered ERA GT Mk 1 at $130,000. Commenter Dwait on the Superformance thread: "Rollers cost 150k and up, depending on options," which sets the floor. ViperNC positioned RCR as "a good alternative for someone that doesn't want to fork out the extra money for the Superformance."

Big-block Ford FE (427/496) or Shelby American engine with documented dyno premium +$60-100k over a small-block or undocumented Roush

Fuel-Injected, Shelby 496 FE-Powered Superformance GT40 Mk I made $325,000 on 24 miles with a DemBeste/Shelby American 496 at 626hp dyno-verified and engine number CSX-P2476-MKI matching the chassis. 496-Powered Superformance GT40 MKII 50th Anniversary Edition made $308,500 with a Shelby 496 FE. By contrast Roush 427IR-Powered Superformance GT40 Mk I could not produce a dyno sheet despite rmoses and gtaylorwill both asking, and stalled at $190,000 before a negotiated $200,000. NewEnglandCobras framed the FE-in-Mk-I as "nearly impossible... with enough money and the right team, the impossible has become reality."

No-reserve listing format premium worth tens of thousands versus the same car with a reserve

No Reserve: Roush 427–Powered Superformance GT40 Mk I is the cleanest natural experiment in the dataset: it failed on BaT in August 2025 and then made $270,000 no-reserve in May 2026 with SLCKJC, WifeSaysNoMore, texasrevving and Nosol fighting in the last 30 minutes. No Reserve: Roush 427IR-Powered Superformance GT40 Mk I went from $157,500 to $229,000 in the final hour. Every reserve car in the sample that anchored to build cost failed.

Roush 427–Powered Superformance GT40 Mk I: seller posted nothing at all; RNM at $201,454. Roush 427IR-Powered Superformance GT40 Mk I: dealer consignment, no cold-start video until the last moment ("Its very hard to upload cold start video last minute, sorry guys"), rhill55 "WTF is the Seller?

Gulf livery in correct period spec with BRM/Halibrand 15-inch knock-offs premium unclear in isolation — colour samples are all n=1 or n=2 — but the highest-clearing cars carry it

No Reserve: Roush 427–Powered Superformance GT40 Mk I ($270,000) and No Reserve: Roush 427IR-Powered Superformance GT40 Mk I ($229,000) are both Gulf-livery cars on 15" knock-offs. Conversely the 18"/19" HRE-shod Roush 427IR-Powered Superformance GT40 Mk I drew criticism from 2112, catpat8000, jetdoctor and MrThunder as "out of place and cheapening the appearance" and underperformed. The statistics explicitly withhold colour medians for thinness, so treat this as directional only.

Non-standard body configuration (roadster conversion, one-off engine swap) discount -25-40% versus a period-correct coupe of the same builder

Roush 427–Powered Superformance GT40 Mk I Roadster sold $140,000 — christophernkennedy asked post-sale "I wonder if this is a record low for a Superformance GT40?" and Deano attributed it to "the non-conventional roadster element." Godzilla-Powered Superformance GT40 Mk I, a globally unique 7.3-litre build with a claimed $385,000 invested, failed at $247,777. The market pays for orthodoxy here.

Usability equipment: functioning A/C, front-axle lift system, EFI over carbs premium +$10-25k, and a working A/C is close to a precondition at the top of the market

Fuel-Injected, Shelby 496 FE-Powered Superformance GT40 Mk I ($325,000) had front-axle lift, A/C and Borla 8-stack injection. Roush 427–Powered Superformance GT40 Mk I was penalised for "A/C leak repaired December 2023, though the system does not blow cold" — phavriluk: "Yet another zillion-dollar toy with broken stuff left for the buyer to sort out." GulfGT40 priced a front-end lift retrofit at roughly $3,000 on the No Reserve car.

289-Powered ERA GT Mark I made $157,000 — the strongest ERA result — on Chuck Gutke assembly, a Curt Vogt engine and original Halibrand magnesium wheels, with ERAFIA vouching for the seller. 302-Powered ERA GT Mk I made $130,000 with dougbrown vouching for the late builder. Race Car Replicas RCR40 Mk I had builder 1889 answering questions in-thread.

Very low mileage on a top-tier car premium +$50-100k at the Superformance end; near-zero effect below $150k

The mileage table is monotonic at the top: 24 mi -> $325,000, 111 mi -> $308,500, 624 mi -> $200,000, 869 mi -> $270,000, 876 mi -> $229,000. But below that it breaks down entirely — 500 mi -> $157,000 while 8,000 mi -> $130,000 and 11,000 mi -> $77,000. Mileage here is a proxy for builder tier, not a driver in its own right. Note also christophernkennedy's warning that low miles signal owners who "are in love with the image" and found the cars hard to live with.

Mileage against sold price across the 13 deep-analysed cars.

Cuts with fewer than 5 cars are left out of the two tables above: Light Blue And Orange Gulf-Style Livery (exterior colour, 1 car), Red With White Stripes (exterior colour, 1 car), Chrysler Intense Blue Pearl (exterior colour, 1 car), Monza Red (exterior colour, 1 car), Blue (exterior colour, 1 car), Red (exterior colour, 2 cars), Dark Blue (exterior colour, 1 car), Blue And Orange Gulf Livery (exterior colour, 1 car), and 3 more. A median of two or three cars is not an estimate of anything, and sorted beside a real one it reads as a price difference that the record does not actually support.

Known issues

majorTitle and registration mismatch — cars titled as something they are not, with California SB100 as the choke point

raised on 10 of the 20 cars deep-analysed

No Reserve: Roush 427–Powered Superformance GT40 Mk I is titled '1969 RCON GT40' rather than Ford GT40, which AmericanMuscles and GulfGT40 flagged as complicating California registration. Race Car Replicas RCR40 Mk I carries "Massachusetts title listing the car as a 1965 Ford Mustang GT." One-Owner, Oldsmobile V8–Powered Tornado Sports Cars GT40 Replica is titled as a 1961 Oldsmobile on original F-85 VIN stamps — Ranchero65 and Shallow-life both raised out-of-state inspection risk, and one commenter noted a plate reader would return a 1961 Oldsmobile sedan. On 351-Powered ERA GT Mk 1 the seller insisted there were no titling problems; Cobalt289 replied with a first-hand account: "All paperwork was submitted, stamped, approved… Then a few weeks later came the rejection letter because it had been flagged. […] there's also California Vehicle Code 4463 that you just might want to take a look at." GT Developments GTD40's title omits the GTD prefix from the chassis number.

Check: Get a photo of the actual title and the VIN plate before bidding. Confirm the titled year/make/model, whether the state calls it Specially Constructed (SPCNS), Reconstructed, Kit, or a real Ford, and whether an SB100 sequence number was issued. Verify your own DMV will accept transfer of that designation. Ask for the MSO/Certificate of Origin and Certificate of Authenticity.

majorCabin heat and inadequate cooling infrastructure — these cars cook their occupants and their brakes

raised on 5 of the 20 cars, including by three separate owners

On Roush 427–Powered Superformance GT40 Mk I, GulfGT40 said the car runs extremely hot inside and cited Jay Leno: "It's the only car he drove where it was 75 degrees outside and 120 degrees inside." Mike831 on the same car itemised what was missing: "Remote oil filter and plumbing along with a 2nd oil cooler and plumbing. I didn't see a trans cooler and plumbing? The ducts are also missing... These cars have little air flow in the wheel wells/under chassis and don't get a lot of air in to cool the brakes." The seller of One-Owner, Oldsmobile V8–Powered Tornado Sports Cars GT40 Replica openly conceded the car "is not happy sitting in extreme heat" above 80°F and had to plan routes around it. RodsHotRod on GT Developments GTD40: "Mine has long legs and needs to be driven, it's not happy puttering around town."

Check: Drive it in traffic on a warm day, not just a cold-start blip. Look for a second oil cooler, remote oil filter, transaxle cooler, brake cooling ducts and twin radiator fans. Confirm the A/C actually blows cold under load with a gauge on it, and check refrigerant type (R12 cars exist in this pool).

moderateNon-functional or misrepresented air conditioning

raised on 5 of the 20 cars

Roush 427–Powered Superformance GT40 Mk I: "A/C leak repaired December 2023, though the system does not blow cold" — the buyer inherits it. On No Reserve: Roush 427IR-Powered Superformance GT40 Mk I the seller first said the switch "does not turn air cold," then said he could not confirm the compressor, then claimed it was "ice cold." On 289-Powered ERA GT Mark I the A/C was uncharged with a suspected bad Sanden seal, and three cans of R12 were thrown in with the car. On 302-Powered ERA GT Mk I the A/C was omitted from the listing entirely until commenters spotted the lines, and Suicide55's question "does it work?" was never answered.

Check: Insist on video of the vent temperature after ten minutes of idling. Check compressor type (Sanden units in the ERA cars repeatedly leak) and whether the system is R12 or R134a.

majorDangerously old tires on low-mileage cars

raised on 6 of the 20 cars

302-Powered ERA GT Mk I ran BFGoodrich Euro T/As dated June 1997 and January 1999. Commenter Era428 described losing control of a near-identical ERA on the same tire model: "I was in complete control, then I wasn't... a change to new, better tires will transform the performance of this car and of course make it much safer." 275GTB, Panteralee, wawrecker and veek all piled on. One-Owner, Oldsmobile V8–Powered Tornado Sports Cars GT40 Replica had rear tires dated September 2005. Roush 427–Powered Superformance GT40 Mk I Roadster had 2012-dated tires at a 2025 sale, and Race Car Replicas GT40 Mk1 was on 2013 Avons.

Check: Read the DOT date codes yourself off all four tires plus the spare. Budget $2,000-3,000 for replacement and note that some period sizes (BFG Euro T/A) are discontinued.

No Reserve: Roush 427–Powered Superformance GT40 Mk I had scuffing through the PPF and into the orange paint on both sides of the front bumper underside, visible only on a lift. racedeck, another SPF owner, was blunt: "The car sits very low, so for those who will actually drive it, you will scrape from time to time." Godzilla-Powered Superformance GT40 Mk I had nose scrapes repaired by Superformance in April 2025 after the gallery photos were shot. 289-Powered ERA GT Mark I and 5.2L Aluminator–Powered Superlite GT-R both disclose splitter/nose scrapes.

Check: Put it on a lift and photograph the underside of the nose and splitter. Ask whether a hydraulic/pneumatic front-axle lift is fitted; if not, budget roughly $3,000 per GulfGT40's estimate.

moderateTransaxle misidentification and transaxle-specific weak points

specification disputed or corrected on 4 of the 20 cars; a structural weakness admitted on 1

On Roush 427–Powered Superformance GT40 Mk I the listing claimed a ZF five-speed; Love-horsepower, Joules5 and christophernkennedy all identified it as a Quaife QBE62G and the seller never corrected it. FordGuy01 did the same on No Reserve: Roush 427IR-Powered Superformance GT40 Mk I: "Enlarge pic #50 and you can see the Q logo on the end plate." 302-Powered ERA GT Mk I was listed as a six-speed and turned out to be a ZF 25-2, with Bmarcum repeatedly demanding tag photos before the seller produced one late. Most seriously, the seller of One-Owner, Oldsmobile V8–Powered Tornado Sports Cars GT40 Replica disclosed that the 901's fifth gear sits on a weak overhung shaft and that the car is driven as a four-speed to avoid loading first gear — a workaround, not a fix.

Check: Photograph the transaxle tag and match it to the claim. Quaife QBE62G is the desirable modern unit; a true ZF 25-2 is fine to ~475hp per the Pantera community; Porsche 901/914 units are marginal behind a V8; Renault 396 is rated 350-400hp.

moderateFiberglass and gelcoat defects: spider cracks, windshield delamination, plexiglass scratches, panel gaps

raised on 7 of the 20 cars

GT Developments GTD40 was disclosed with a cracked rear window and "areas of delamination around windshield." One-Owner, Oldsmobile V8–Powered Tornado Sports Cars GT40 Replica had "spider cracks in hood finish, paint wear near wheel well edges." On Race Car Replicas RCR40 Mk I, iamrobertm found a B-pillar paint blemish and driver's-window plexiglass scratches. Worst case is 302-Powered Ardern Cars Active Power GT at 6 miles: LS3Frank found a hairline crack in the driver-side wheel well that the seller first said was fixed then admitted "it's still cracked," plus bondo on the passenger skirt and, per AmericanMuscles, a frunk "sticking up about an inch" — seller graded his own fitment "8 out of 10."

Check: Inspect gelcoat around wheel arches, hood, B-pillars and clamshell edges in raking light. Check windshield perimeter for delamination (moisture path) and press-test panel latches. Verify decals versus paint for stripes and roundels.

majorBuild cost is not resale value — sellers anchoring on invoices consistently fail to sell

the direct cause of 4 of the RNM results in the sample; sell-through overall is only 60.7%

Godzilla-Powered Superformance GT40 Mk I: $385,000 claimed investment, RNM at $247,777. christophernkennedy: "This is a strange result—$385K invested, just a little over 100 miles, and apparently 'really close' to selling at $248K?" Roush 427IR-Powered Superformance GT40 Mk I: described by the seller as a $330,000 build, stalled at $190,000, negotiated at $200,000 — a 39% shortfall. 5.2L Aluminator–Powered Superlite GT-R: $152,000 documented spreadsheet, RNM at $116,111. 302-Powered Ardern Cars Active Power GT: RNM at $67,500, which jlwdvm called "WAY below the price of the kit and parts to put this car together." Even the top of the market retraces: 496-Powered Superformance GT40 MKII 50th Anniversary Edition sold $386,000 in February 2024 and $308,500 in June 2025 — 20% in sixteen months.

Check: Ignore the build spreadsheet. Price off the comparable table by builder tier, then subtract for the specific defects. Ask what the seller's reserve is before you spend money on an inspection.

moderateUndocumented engine specification — no dyno sheet, no build sheet, spec changed mid-build

raised on 6 of the 20 cars

On Roush 427IR-Powered Superformance GT40 Mk I, rmoses asked twice for the "HP rating and spec sheet from Roush" and got nothing. On Race Car Replicas RCR40 Mk I, builder 1889 appeared to say "It was originally built with a 302 based engine. I'm curious when the engine was replaced?" — the current 351 was a substitution after an intake ordering error, and the seller's 410-450hp figure is a guess. Godzilla-Powered Superformance GT40 Mk I was never dynoed as assembled: "we preferred not to stress our brand new $50k engine with a dyno." Even the $325,000 Fuel-Injected, Shelby 496 FE-Powered Superformance GT40 Mk I had its seller calling the engine a 427 until NewEnglandCobras corrected him: "This is not a 427ci engine... bored and stroked to 496ci."

Check: Demand the engine builder's invoice and dyno sheet, and match the engine serial to the paperwork. Confirm whether it is a Windsor or an FE, and the actual displacement.

moderateErgonomics: the cars do not fit tall drivers and lack modern safety provision

raised on 4 of the 20 cars

Race Car Replicas GT40 Mk1 was "designed for 5'8" driver; taller drivers would require seat repositioning or Gurney Bubble modification." The seller of One-Owner, Oldsmobile V8–Powered Tornado Sports Cars GT40 Replica (5'11", 180lb) said a 6'2" occupant would be tight. 5.2L Aluminator–Powered Superlite GT-R also carries a seller-noted height restriction. On No Reserve: Roush 427–Powered Superformance GT40 Mk I, oldxotix warned: "These are serious performance machines, and are pretty much devoid of any safety features... you will likely exceed your driving skills before you reach the limits of the car."

Check: Sit in it before bidding. Confirm whether a Gurney bubble roof panel is fitted (driver's side), whether the pedal box is adjustable, and what the seat rails allow.

On Roush 427IR-Powered Superformance GT40 Mk I, pjr273 wrote: "someone drilled into the body to add canards and a splitter. I have so many questions…" and got no reply. fitfan observed "the wheel arches / cut out look all wrong? (cut out much bigger and have a lip?)" — also unanswered. DaveSC, a Superformance owner since 2011 with 24,000 miles, confirmed "The canards and front splitter were installed after the car arrived in the U.S." and added the caution that matters: "These are great cars to own but they require some detailed knowledge to maintain them properly."

Check: Compare the car to the original builder's spec sheet. Look behind splitters and canards for through-body fasteners and evidence of arch cutting.

majorChassis corrosion and jack damage on older continuation/monocoque cars

significant on 1 of the 20 — but it was the most expensive failure in the sample

On 1981 Safir GT40 Mk V Roadster, Legendcobra worked through the photos and flagged corrosion that had "rounded the squared edge of folded and spot-welded chassis" (picture 90), an apparently enlarged floor drain hole (picture 106) and a possibly bent monocoque (picture 107), concluding "This car looks like many years of careless floor jack use. Those bulkheads look bent." The seller dismissed these as surface issues and never addressed picture 107. Reserve not met at $300,000.

Check: On any steel-monocoque Safir or early continuation, inspect the rear bulkhead, floor drains and sill folds for corrosion and distortion. Get it on a lift with a specialist.

moderateSuperformance's corporate status

raised once, by an experienced owner

On No Reserve: Roush 427–Powered Superformance GT40 Mk I, ViperNC referenced that Superformance had ceased operations. This is a single unverified comment, not a confirmed fact, but it is material to the brand premium described above and worth independently confirming before you pay $250,000+ for the badge.

Check: Confirm parts and service availability for chassis-specific components before paying a Superformance premium; identify which authorised builder (Olthoff, V's Performance, Jo's Garage, Airpark) can support your car.

Pre-purchase checklist

Ask the seller

  1. What exactly does the title say — year, make, model, and body-type designation (SPCNS, Reconstructed, Kit, or Ford GT40)? Can you send a photo of it and of the VIN plate?
  2. Was an SB100 or equivalent specially-constructed-vehicle number issued, and can I see the paperwork? Has the car ever been rejected or flagged by a DMV?
  3. Who built the engine, what does the invoice say, and can I see a dyno sheet with the engine serial? Is it a Windsor or an FE, and what is the actual displacement?
  4. What transaxle is fitted — send me a photo of the tag. Has it ever been rebuilt, and by whom?
  5. Who assembled the car and are they still contactable? Can you put me in touch with the original owner?
  6. Does the A/C blow cold right now, on video, after ten minutes idling? What refrigerant?
  7. What are the DOT date codes on all four tires?
  8. Why are the miles so low, and what has the car actually done — has it ever been on track, on a rally, or in traffic on a hot day?
  9. Is a front-axle lift fitted? What does the underside of the nose and splitter look like on a lift, photographed from below?
  10. Has any bodywork been drilled or modified after delivery — splitter, canards, arches, wheel diameter changes? Do the original wheels come with it?
  11. What is your reserve? (And if the car has been listed before on BaT, eBay or elsewhere, at what number and why did it not sell?)
  12. What is on the car's to-do list right now that you have chosen not to fix, and what would it cost?
  13. What spares come with it — second front clamshell, alternate wheels, Weber kit, spare steering wheel? Send a list.

Walk away when

Budget

Driver-grade, $85,000–$130,000: a sorted 1980s-90s British or US kit-based car — GT Developments GTD40 territory at $96,500, a Race Car Replicas RCR40 Mk I at $107,000, an ERA at $130,000. Expect to spend $5,000–$15,000 immediately on tires, fluids, A/C and cooling. Below about $80,000 you are into owner-engineered specials (the $77,000 Tornado) where the documentation and the builder's reputation are the whole asset; below $20,000 you are buying 1960s-70s Fiberfab-class kits that are parts cars.

Strong, $150,000–$230,000: the best ERAs with real provenance ($157,000 for 289-Powered ERA GT Mark I) or an entry-level Superformance Mk I with Roush 427 power ($200,000–$229,000). This is the sweet spot of the market and where the 75th percentile sits at $228,000. At this level insist on a dyno sheet, a working A/C, current-date tires and a title you can register.

Best-in-class, $270,000–$330,000: a low-mileage Superformance with a Shelby FE big block, front-axle lift, EFI, correct 15-inch knock-offs and a live, engaged seller — $270,000 for the no-reserve Gulf Roush car, $308,500 for the 50th Anniversary MkII, $325,000 for the 496 FE. Above roughly $330,000 the record is thin and unkind: only one sale in 84 has ever exceeded it ($386,000, February 2024) and that same car resold 20% lower.

A sanctioned Safir Mk V continuation is a different asset class and, on the one data point available, could not find $300,000 with chassis questions hanging over it.

Outliers

Fuel-Injected, Shelby 496 FE-Powered Superformance GT40 Mk I

Fuel-Injected, Shelby 496 FE-Powered Superformance GT40 Mk I $325,000

Top of the entire deep sample and 132% above the all-time $140,000 median. A genuinely rare combination — Shelby American 496ci FE in a Mk I body, 626hp dyno-verified, chassis-matching CSX engine number, Borla 8-stack, front lift, A/C, 24 miles, documented ~$300k of invoices. Bidding was competitive to the end (Texshooter vs LVT5015 from $280k) even though the seller never produced the promised running video and had misdescribed the engine as a 427 until NewEnglandCobras corrected him. This is what best-in-class currently costs, not a repeatable number for an ordinary Superformance.

496-Powered Superformance GT40 MKII 50th Anniversary Edition

496-Powered Superformance GT40 MKII 50th Anniversary Edition $308,500

A high absolute price that is simultaneously the clearest evidence of softness at the top: the same car sold for $386,000 in February 2024 — a 20% loss in sixteen months. One of 20 built, Shelby FE 496, 111 miles. Its rear frame was repaired and support struts fabricated during a June 2024 clutch service, which the seller only explained after BloodyHell pressed.

No Reserve: Roush 427–Powered Superformance GT40 Mk I

No Reserve: Roush 427–Powered Superformance GT40 Mk I $270,000

Failed on BaT in August 2025 with a reserve, then made $270,000 with a new consignor and no reserve. Same basic car as the $200k and $229k Roush cars, but with a responsive seller, full service records and Gulf livery. AmericanMuscles' verdict — "Pretty much at the roller price with shipping and taxes still…" — is the market telling you labour is free.

Roush 427–Powered Superformance GT40 Mk I Roadster

Roush 427–Powered Superformance GT40 Mk I Roadster $140,000

The bargain of the sample and possibly a record low for a Superformance GT40 (christophernkennedy raised exactly that question, and TheGuesser noted "You'd probably see this listed on a dealer's lot for well over $200k"). Roush 427R with Hilborn ITB EFI, A/C, well-documented, well-driven — but the non-original roadster conversion cost it roughly $70-90k against coupe comps. Deano: "the non-conventional roadster element on this one kept the price down."

Race Car Replicas RCR40 Mk I

Race Car Replicas RCR40 Mk I $107,000

Sold $37,000 below what a sister RCR failed to make six months earlier (Race Car Replicas GT40 Mk1, RNM at $144,000). Aluminium monocoque, Porsche G50, 351 ITB, builder present in the thread, five-year single ownership. Commenters called it a "deal of a lifetime" and iamrobertm publicly regretted missing it. The seller set a reserve "dramatically lower than the last" RCR — and got a sale.

One-Owner, Oldsmobile V8–Powered Tornado Sports Cars GT40 Replica

One-Owner, Oldsmobile V8–Powered Tornado Sports Cars GT40 Replica $77,000

A remarkable result for a 1998 owner-built kit on an Oldsmobile 266ci and a Porsche 901 transaxle, titled as a 1961 Oldsmobile. It cleared $77,000 purely on documentation and builder credibility — build journal, receipts, hand-written notes, a spare-parts hoard including two running engines, plus TSheedy's first-hand account of a three-hour mountain drive at 100mph+ where "the GT ran flawlessly." Proof that transparency is worth real money at the bottom of the market.

No Reserve: Fiberfab Avenger GT12 Project

No Reserve: Fiberfab Avenger GT12 Project $4,100

The floor of the entire dataset ($2,500 is the all-time low). A non-running VW-floorpan Fiberfab with a missing ignition key, deteriorated interior and underside rust, sold with the seller saying "Don't know if it drives though… that's your problem." bugnbox noted the genuine Porsche 356 1.6 engine alone "is worth probably double the bid price" — it sold as a parts car, which is what these are.

1981 Safir GT40 Mk V Roadster

1981 Safir GT40 Mk V Roadster $300,000

The most expensive failure in the sample. A sanctioned Safir continuation, chassis number 1, original-owner Peter Thorp provenance, literature-documented — and still unsold at $300,000 after Legendcobra worked through the photographs and identified probable rear bulkhead corrosion, an enlarged floor drain, and a possibly bent monocoque that the seller never addressed. Continuation provenance does not survive chassis doubt.

Godzilla-Powered Superformance GT40 Mk I

Godzilla-Powered Superformance GT40 Mk I $247,777

Reserve not met at $247,777 on a claimed $385,000, 1,000-labour-hour, SEMA/PRI show build — the sharpest illustration that this market will not pay for uniqueness or for labour. No dyno on the assembled engine, 125 miles, one-of-one engineering with no reliability precedent. sliproc's read was that it showed "how soft the market is right now rather than the car itself"; the more likely reading is that buyers will not underwrite an unproven one-off.

Verdict

Three real limitations. First, only 13 of the 84 completed auctions have coded mileage and transmission data, so the mileage-versus-price table and the single 'Manual: $140,000 (n=13)' transmission median are describing a sixth of the market — and since essentially every GT40 replica is a manual, that median carries no comparative information at all. Second, all exterior-colour medians were withheld for thinness (every colour has one or two cars), so my Gulf-livery premium is inferred from which cars happened to clear highest and should be treated as directional, not measured. Third, the by-year medians move violently on samples of one to two cars (2016 n=1, 2020 n=1, 2026 n=2) and are dominated by builder mix; the only trend figure I would put weight on is the +5.1% rolling twelve-month comparison ($165,000 vs $157,000), and even that is a small-sample move. The deep-analysed set is the 20 most recent sales, which skews toward 2025-26 and toward Superformance; older GTD, CAV and DAX-era cars in the full 84 are not represented in the comment-thread evidence. Frequency counts like 'raised on 10 of 20 cars' therefore describe the recent listings I was given, not the whole record. Finally, almost all of the failure-point evidence comes from BaT commenters — knowledgeable strangers, not inspectors. I have weighted claims that recur across multiple unrelated listings (titling, cabin heat, ancient tires, ground clearance) and claims corroborated by identifiable owners or builders (DaveSC, 1889, DeanVintageRacing, ViperNC, Panteralee, Legendcobra) far above one-off assertions. Single-source items I would verify independently rather than act on: ViperNC's statement that Superformance has ceased operations, the various claims about what California will and will not register, and Legendcobra's photo-based diagnosis of a bent monocoque on the Safir.

A superb Superformance GT40 roadster replica with a potent Roush 427R and exceptional driving pedigree, but the unconventional topless conversion and replica provenance likely held final price well below comparable coupe builds.
Roadster configuration may limit appeal · Replica car, not original GT40; historical significance is limited to build quality and performance, not authenticity · Roadster conversion is custom modification that may limit appeal to purists; only one authentic GT40 Mk1 roadster prototype (Safir Mk5) exists per Legendcobra comment
496-Powered Superformance GT40 MKII 50th Anniversary Edition
$308,500
· 111 mi · manual · black
A museum-quality 50th Anniversary GT40 MKII with flawless execution and Le Mans provenance, recently sorted and estate-cleared, that sold at a steep 20% haircut from its prior auction despite competitive final bidding—watch whether this signals a market correction or merely reflects the prior example's inflated price.
Prior owner deceased; car passed through estate, motive and history for low mileage unusual · Significant price drop from $386,000 (Feb 2024 sale) to $308,500 (June 2025), 20% loss in one year
Godzilla-Powered Superformance GT40 Mk I
Reserve not met
· 125 mi · manual · gulf blue and orange
A globally unique, meticulously engineered one-of-a-kind Godzilla GT40 with extraordinary spec but zero field-tested reliability, unproven market value, and an owner pattern of build-to-flip rather than ownership—reserve not met at nearly a third of claimed build cost signals either serious overvaluation or legitimate buyer caution about untested execution and component longevity.
Wide-body Godzilla engine installation unprecedented; engineering complexity unproven in field · Scrapes on nose underside · Reserve not met at $247,777 despite claiming $385,000 invested; significant gap between build cost and market value suggests overvaluation or lack of buyer confidence · Seller admits owner sold previous car (300 miles) after 18-month build; pattern of builds-to-flip rather than ownership suggests speculative intent by original buyer
No Reserve: Fiberfab Avenger GT12 Project
$4,100
· 3,500 mi · manual · yellow
A genuinely rare 356-powered Fiberfab time capsule that fired up just before auction but remains structurally, mechanically, and electrically unverified—sold well below the replacement cost of its Porsche engine alone, suggesting the buyer either knew something about resale value or was taking a calculated flyer on a non-running project.
Engine non-running at start of ownership · Interior deterioration · Engine not run under current ownership until shortly before auction · Ignition key missing
No Reserve: Roush 427IR-Powered Superformance GT40 Mk I
$229,000
· 876 mi · manual · light blue with orange accents gulf-style livery
A mechanically impressive Superformance GT40 replica with period-correct Gulf livery and modern 427 power hindered by inconsistent seller communication on AC functionality, questionable suspension geometry, and unexplained seven-year ownership with minimal use.
AC status unclear and inconsistent · Stance/suspension height questionable · Seller inconsistent on AC functionality—initially said non-functional, later confirmed ice-cold; compressor visible in photos but seller claimed uncertainty · Stance noticeably higher than original GT40 design; multiple knowledgeable commenters flagged aesthetic/design concerns
1981 Safir GT40 Mk V Roadster
Reserve not met
· 18,000 mi · manual · red
A historically significant and rare first-of-series Safir continuation with documented Ford blessing and proper engineering, undermined by visible chassis distortion, mileage uncertainty, and a failed $300k reserve that exposed a sizable valuation gap despite strong provenance and enthusiast support.
Possible rear bulkhead corrosion and distortion · Possible bent monocoque · Seller did not initially disclose specific details about visible corrosion and chassis distortion when challenged directly; only addressed them after photos were cited · Mileage listed as TMU with uncertainty about total distance traveled under multiple ownerships
Race Car Replicas GT40 Mk1
Reserve not met
· 2,800 mi · manual · white with red and black stripes
An obsessively engineered, media-famous GT40 Mk1 replica with impeccable provenance, proven sorting, and sub-2300 lbs lightness that failed to clear reserve at $144k, suggesting either an unrealistic seller expectation or genuine market skepticism about GT40 replica values despite universal praise for the build.
Reserve not met at $144,000 final bid, suggesting valuation mismatch or market uncertainty for replica GT40s · Tires appear original to 2013 build with minimal miles but full decade of age; would benefit from replacement prior to driving
302-Powered ERA GT Mk I
$130,000
· 7,600 mi · manual · yellow
A genuinely well-built ERA by a meticulous original owner with 20 years of proven reliability and actual use, held back by critical tire age, unaddressed fuel-cell deterioration, and listing errors that signal seller inexperience—but at $130k, a mechanically sound and documented example that justifies buyer enthusiasm if tire and fuel work are budgeted immediately.
Tires extremely outdated · Foam-filled fuel cells potentially deteriorated · Listing errors: transmission spec (6-speed vs 5-speed ZF) not corrected by seller or BAT until community pressure; A/C omitted entirely from description despite being present · Title shows 1992 but car completed in 2001; titled as '1992 Custom GT4' which may complicate registration in some states (Era428 reported California collector-car licensing challenges with mismatched year)
289-Powered ERA GT Mark I
$157,000
· 500 mi · manual · red
A meticulously detailed ERA GT40 tribute with authentic period-correct 289 Hi-Po power and strong provenance from respected builder and original Shelby-connected owner, though no dyno verification and title-manufacture-date mismatch warrant standard pre-purchase inspection, ultimately sold for $157k to an enthusiastic first-time collector.
Car titled as 1966 Ford despite being built in 1990—may complicate registration/insurance in some jurisdictions · Only 500 miles shown after 35 years; previous owner in Connecticut for ~25 years with minimal driving, then rapidly sold and extensively serviced by current owner within one year before auction
302-Powered Ardern Cars Active Power GT
Reserve not met
· 6 mi · manual · grigio silverstone (gray) with silver stripes
A capable and well-equipped Ardern GT40 replica with a new engine and all-new parts, but multiple assembly defects, non-functional design elements, and a problematic kit-car title conspired to send it across the auction block well below reserve despite expert workmanship and functionality.
Hairline crack in driver-side wheel well · Damage to passenger-side skirt with bondo appearance · Only 6 miles driven despite completion in 2024; seller selling immediately after build (same pattern as previous builds sold with minimal mileage) · Multiple assembly damage issues acknowledged by seller (cracks, dents, bondo work)
