Essentially new with 89 miles, Race Red paint, and the desirable six-speed manual, it is on Cars and Bids at $35,000 with six days to go.2026 Ford Mustang Dark Horse PremiumCars & BidsWhat it's worth right nowThe Dark Horse Premium starts high, and this one adds a supercharger on top. According to Ford and current pricing, the Dark Horse Premium starts at $71,765 and a well-optioned example like this one, with the Handling Package and Tech Pack, stickers in the $73,000 to $80,000 range, before the seller added a Whipple kit that runs around $15,000 in parts and installation.AdvertisementAdvertisementThat combined cost is the key context: modified cars sell for less than the sum of their parts. The warrantied supercharger build and essentially-new condition support strong money, while the considerations below place it below its as-built total.2026 Ford Mustang Dark Horse PremiumCars & BidsWeighing the low mileage and big-power build against those points, fair value realistically lands in the $68,000 to $85,000 range, most likely the mid-to-high $70,000s. At $35,000 with six days remaining and a reserve in place, the bidding should climb into that band.Condition and detailsThe car is essentially new and heavily built. Finished in Race Red over black and blue, it carries the Dark Horse Handling Package, the Tech Pack, Brembo brakes, a Torsen limited-slip differential, and oil, transmission, and differential coolers, with the 500-horsepower Coyote V8 fed by a Whipple supercharger kit for a claimed 810 horsepower through a six-speed Tremec TR-3160 manual. It also wears 20-inch RTR wheels with new Pirelli Trofeo tires, an aftermarket lip and side skirts, and carbon-fiber accents, and the sale includes the factory 19-inch wheels, a car cover, and the window sticker.2026 Ford Mustang Dark Horse PremiumCars & BidsA few points deserve attention. The 810-horsepower figure is the seller's claim, as no dyno sheet was provided, so treat it as estimated, and confirm the supercharger's warranty coverage and how it affects the Ford powertrain warranty, the seller indicated the blower was purchased and warrantied through a Ford dealer but was unsure whether the term is one or three years, so nail that down. There is also a loan on the car, and the sale proceeds will pay it off, so the title may only be available after payoff; coordinate that through the platform's secure payment process.2026 Ford Mustang Dark Horse PremiumCars & BidsTwo more notes: the modifications may not pass emissions in some states, so confirm registration requirements where you live before bidding, and the combined roughly $88,000 to $95,000 as-built cost will not be fully recouped, which is normal for a modified car. It is otherwise an as-new, 89-mile car with new tires and the factory wheels included, and a pre-purchase inspection rounds it out.2026 Ford Mustang Dark Horse PremiumCars & BidsAdvertisementAdvertisementThe offerSpecificationDetailMakeFordModelMustang Dark Horse PremiumYear2026Mileage89 milesEngineSupercharged 5.0-liter V8Power810 hp claimed by the seller (500 hp stock)Transmission6-speed manualDrive typeRear wheel drive with Torsen limited-slip differentialExterior colorRace RedInterior colorBlack and blueCurrent bid$35,000, with six days leftInterested in this 2026 Ford Mustang Dark Horse Premium? View the listing here.What makes the Dark Horse Premium uniqueThe Dark Horse is the most track-focused version of the S650 Mustang, positioned above the GT as the spiritual successor to the Mach 1. It uses the most powerful naturally aspirated version of Ford's 5.0-liter Coyote V8, rated at 500 horsepower, along with a specific body kit, unique badging, a titanium shift knob, and chassis and suspension upgrades. Crucially for enthusiasts, it offers a Tremec six-speed manual with rev matching, one of the best manual gearboxes available today, and this example pairs that with a stronger TR-3160 unit suited to the added torque. The Whipple supercharger then transforms it, nearly doubling the output to a claimed 810 horsepower.2026 Ford Mustang Dark Horse PremiumCars & BidsThat combination of the Dark Horse's factory hardware, a proper manual transmission, and a supercharger's brute force is what makes this build so compelling. It marries the newest Mustang's modern platform and sharp handling with genuinely ferocious power, all in essentially new condition.My takeThis is a seriously fast, essentially new Mustang, and the manual makes it special. The Dark Horse is already an excellent platform, and the addition of a warrantied Whipple supercharger turns it into a monster, while the six-speed manual keeps it engaging in a way the automatic cannot match. With 89 miles, Race Red paint, and the factory wheels included, it is about as close to new as a modified car gets.AdvertisementAdvertisementFair value sits in the $68,000 to $85,000 range, below the roughly $90,000-plus as-built cost because modified cars do not recoup their full investment, so the bidding has room to climb toward the reserve. Go in with the details handled: confirm the supercharger warranty term and a dyno to substantiate the 810-horsepower claim, coordinate the loan payoff so the title transfers cleanly, and verify you can register it in your state. Handle that, and you have a barely driven, big-power manual Mustang for well under what it cost to build.Disclaimer: This post is for informational purposes only. We are not a dealership or broker.
