The ACR set production lap records at more than a dozen tracks, and the Extreme package's downforce is a big reason why. Offered at no reserve with an essentially untouched odometer, this is a blue-chip, end-of-an-era collectible, and the bidding reflects it.2017 Dodge Viper ACR ExtremeBring a TrailerWhat it's worth right nowClassic.com shows the fifth-generation Viper ACR averaging around $272,017, with a low of $186,000 and a recorded high of $593,500 for a 2017 VoooDoo II Edition ACR Extreme in March 2026. The ACR Extreme cars, with their record-setting aero, sit at the upper end of that market, and delivery-mileage examples in desirable specifications command the strongest numbers.AdvertisementAdvertisementThis car has the ingredients that push toward the top: it is a final-year 2017, it has the full Extreme Aero Package plus the carbon-fiber options, and at 52 miles it is essentially untouched. The seller emphasizes it is a one-of-one build with all three carbon-fiber options, and the enthusiastic ACR community in the comments is projecting figures well above the average, with several suggesting $700,000-plus. The no-reserve format guarantees it sells, which tends to draw serious, committed bidders.2017 Dodge Viper ACR ExtremeBring a TrailerGiven the delivery mileage, the Extreme Aero and carbon options, and the final-year status, I would call fair value roughly $500,000 to $700,000, a wide band reflecting how thin and specification-sensitive the top of this market is. The current $495,000 bid with twenty-four bids and five days remaining is already in that territory and climbing, consistent with the strong interest.Condition and detailsThe specification is the story. This GTC ACR is finished in matte Venom Black with the exterior carbon-fiber package and the Extreme Aero Package, which adds a front splitter, a vented hood, a rear diffuser, a carbon-fiber rear wing, and upper dive planes for nearly a ton of downforce at speed. It carries the ACR and ACR Interior packages, Customer Preferred Package 22L, Brembo carbon-ceramic-matrix brakes, Bilstein manually adjustable suspension, 19-inch ACR Venom wheels on Kumho track tires, and Sabelt seats with red-stitched Alcantara. The hand-assembled 8.4-liter V10 makes 645 horsepower through the Tremec six-speed manual, and clear paint protection film was applied in July 2026.2017 Dodge Viper ACR ExtremeBring a TrailerFor condition, this is effectively a brand-new car with 52 miles and a clean Carfax, offered with the owner's manual, spare parts, and a car cover with carrying bag. On a delivery-mileage collectible like this, the priorities are confirming the car is exactly as represented and unmodified, verifying the specification and any build documentation, and establishing the tire and fluid situation, since even a 52-mile car has aging consumables, and the Kumho track tires in particular have a shelf life.2017 Dodge Viper ACR ExtremeBring a TrailerThe diligence is otherwise light given the mileage, but the stakes are high. Confirm the one-of-one build claim and the complete options list with documentation, verify the car has been properly stored, and treat this as the preservation-grade investment piece it is, meaning the decision to keep it as a static collectible or ever drive it will define ownership. The car is a no-reserve dealer offering, so it will sell to the high bidder; a buyer at this level should still arrange verification of the car's originality and history.2017 Dodge Viper ACR ExtremeBring a TrailerAdvertisementAdvertisementThe offerSpecificationDetailMakeDodgeModelViper ACR Extreme (GTC)Year2017Mileage52Engine8.4-liter V10Power645 horsepower, 600 lb-ftTransmissionTremec six-speed manualDrive typeRear-wheel drive with limited-slip differentialExterior colorMatte Venom BlackInterior colorBlack leather with AlcantaraCurrent bidUSD $495,000 (no reserve)Interested in this car?

That package produced the highest aerodynamic downforce of any production car of its era, nearly a ton at top speed, through an adjustable front splitter, additional dive planes, an extended rear diffuser, and a huge adjustable carbon-fiber rear wing. That aero, combined with the ACR's bespoke carbon-ceramic Brembo brakes, adjustable Bilstein suspension, and the hand-assembled 8.4-liter V10, let the ACR set production lap records at more than a dozen tracks including Laguna Seca.2017 Dodge Viper ACR ExtremeBring a TrailerAs the Viper was discontinued after 2017, the final-year ACR Extreme cars have become the definitive send-off for one of the last analog, naturally aspirated, manual-only American supercars. Values reward low mileage, the Extreme Aero and carbon options, and special editions, with the very best cars, like the record $593,500 VoooDoo II, reaching well into the mid-six figures. A 52-mile, fully carbon-optioned final-year Extreme sits squarely in that blue-chip conversation, which is why it belongs in a premium no-reserve listing and why the enthusiast community is watching it so closely.My takeThis is a genuine end-of-an-era collectible: a final-year Viper ACR Extreme with the full carbon-fiber options and just 52 delivery miles, offered at no reserve so it will find its true market number. My fair-value call is $500,000 to $700,000, reflecting the delivery mileage and top specification against how narrow and spec-sensitive the very top of the ACR market is. The current $495,000 bid is already in that range with room to climb.AdvertisementAdvertisementThe buying advice is about verification and preservation. Confirm the one-of-one build and complete options list with documentation, verify the car's storage and originality, and address the aging tires and fluids that even a 52-mile car will have. Decide up front whether this is a static collectible or a car you would ever exercise, since that shapes everything about owning it. Handle that, and the current $495,000 no-reserve bid is a fitting figure for one of the last and most extreme Vipers Dodge ever built.Disclaimer: This post is for informational purposes only.
