This 2026 example shows 4,176 miles and is listed at a Nevada dealer. It carries an asking price of $127,800. Although the listing labels it a CT5, the supercharged 6.2-liter V8 confirms it is the range-topping Blackwing.2026 Cadillac CT5-V BlackwingduPont RegistryWhat it's worth right nowThe CT5-V Blackwing has proven to be one of the strongest value-holders in the performance-sedan class. According to Kelley Blue Book, the 2026 Blackwing starts at $100,695, with well-optioned examples reaching close to $130,000, and strong demand has kept used values near their original stickers.2026 Cadillac CT5-V BlackwingduPont RegistryFair value for a nearly new, well-optioned example sits close to $108,000 to $130,000, most likely close to $116,000 to $124,000. The $127,800 asking price lands at the upper end of that range, in line with a low-mileage, well-optioned car, though confirming the exact packages against the window sticker matters, since the listing does not detail them.Condition and detailsThe listing is light on specifics, so a buyer should fill in the gaps. It confirms 4,176 miles, a black exterior over a gray interior, rear-wheel drive, an automatic transmission, and the supercharged 6.2-liter V8, with the options list, packages, and history not specified by the seller. That engine is the telling detail, since the 6.2-liter supercharged V8 is exclusive to the Blackwing, so this is the 668-horsepower flagship rather than a lesser CT5.2026 Cadillac CT5-V BlackwingduPont RegistryAt close to delivery mileage the car should present as new, but the full accounting is worth requesting. A buyer should ask for the window sticker and complete build to confirm the packages, colors, and any special-edition content, along with a clear statement of any dealer fees. It is worth noting this is the automatic rather than the six-speed manual, which is the quicker configuration but the less scarce of the two among collectors. Confirming the remaining factory warranty and a clean history rounds out the essentials, and a pre-purchase inspection is sensible even on a near-new car.2026 Cadillac CT5-V BlackwingduPont RegistryAdvertisementAdvertisementThe offerSpecificationDetailMakeCadillacModelCT5-V BlackwingYear2026Mileage4,176 milesEngine6.2-liter supercharged V8Power668 hp and 659 lb.ft of torqueTransmission10-speed automaticDrive typeRear-wheel driveExterior colorBlackInterior colorGrayAsking price$127,800Interested in this 2026 Cadillac CT5-V Blackwing? View the listing here.What makes the CT5-V Blackwing uniqueThe CT5-V Blackwing occupies a genuinely special place in the modern performance landscape, delivering a formula that its German rivals have largely abandoned. Where the BMW M5 and Mercedes-AMG models have grown heavy with hybrid systems and all-wheel drive, the Blackwing keeps things gloriously analog, sending 668 horsepower from its hand-built supercharged 6.2-liter V8 to the rear wheels, with a six-speed manual offered as standard and this automatic as the alternative. That combination of a thunderous pushrod V8, rear-wheel drive, and a real driver focus gives it a character all its own, and it launches to 60 mph in the low three-second range while still coddling four occupants in a comfortable, well-appointed cabin.2026 Cadillac CT5-V BlackwingduPont RegistryThat blend of brutal performance, everyday usability, and relative value has made the Blackwing a critical darling, earning a place on Car and Driver's 10Best list for five consecutive years. With supercharged V8s facing an uncertain future across the industry, the CT5-V Blackwing has taken on the feel of a modern classic in the making, which is a large part of why these hold their value so tenaciously.My takeThe CT5-V Blackwing is one of the most compelling performance sedans on sale, and a nearly new example is a smart way into one, since these barely depreciate and the supercharged V8 formula grows rarer by the year. In black over gray, with delivery mileage, this is a serious, ferocious machine that also happens to be a sound financial proposition, an unusual combination in a car this quick.AdvertisementAdvertisementFair value sits close to $108,000 to $130,000, most likely close to $116,000 to $124,000, essentially at the asking price for a well-optioned, low-mileage car. Before committing, confirm the full specification and packages against the window sticker, clarify any dealer fees, verify the factory warranty and history, and arrange an inspection. Handle that, and this is a genuine modern muscle-sedan icon bought while it is still nearly new.Disclaimer: This post is for informational purposes only. We are not a dealership or broker.
