Cadillac spent the final years of the CT6 doing something the brand rarely gets credit for: building a genuinely fast, genuinely rare full-size sedan. Now one of them is live on Cars & Bids, a 2019 Cadillac CT6-V with 49,800 miles, a hand-built twin-turbo V8, and a high bid of $24,750 with six days left on the clock.
The Blackwing Before the Blackwing Boom
Under the hood is a 4.2-liter twin-turbocharged V8 with two twin-scroll turbos, forged connecting rods, and a forged crankshaft, all assembled by hand. It makes 550 horsepower and 640 lb-ft of torque, sent to all four wheels through a 10-speed automatic. The listing cites a 0-to-60 time of 3.8 seconds, which is supercar-adjacent territory for a four-door that seats five adults in comfort.
Motorious readers know the Blackwing name from the modern CT5-V, which has gone head to head with the Camaro ZL1 and outrun a Lamborghini Huracán and a Mustang in a 161-mph showdown. The CT6-V is where that engineering story started, and far fewer people noticed it. Fewer than 1,000 CT6-V sedans were built for North America, and this is one of just 915 produced for the U.S. market, per the enthusiast site Cadillac Society.
What Comes With It
This example is finished in Crystal White Tricoat over a Jet Black interior and carries a clean Washington title. The digital window sticker in the gallery lists 20-inch Midnight Silver wheels, Magnetic Ride Control, dual sunroofs, heated and ventilated front seats, heated rear seats, a rear-seat entertainment system, Bose Panaray audio, and adaptive cruise control. The seller reports no notable modifications.
The story behind the sale is a good one. The seller bought the car as a bucket-list purchase, spent nearly a year driving it across the country, and says it was never used as a daily driver. The seller’s driving days are coming to a close and the household is going down to one vehicle, so it is time to let someone else enjoy it.
Service records show an October 2025 visit for rear differential fluid, coolant, brake fluid, an oil change, and wipers, plus an alignment and new tires in March 2025. The Carfax shows regular oil changes at 26,303, 34,444, and 42,639 miles.
A car this rare deserves a careful look before bidding. The Carfax lists “minor damage” in March 2025 and again in October 2020, and the seller says the passenger side was struck in a low-speed collision, with repair documentation included in the gallery. Disclosed cosmetic flaws include chips and scratches around the exterior, scuffs on the lower front bumper, curb rash on the passenger-side wheels, and some wear on the driver’s seat bolster. All of that is worth weighing against a $24,750 bid for a hand-built flagship that cost far more when it was new.
Why It Deserves Attention
The CT6 went out of production in 2020, ending its brief reign atop the Cadillac range, and the market has been busy chasing SUVs ever since. That leaves cars like this one in an odd spot: too new to be a classic, too rare to be ordinary, and too quick to be dismissed as a luxury barge. We have been tracking this corner of the market for a while, from another 2019 CT6-V pitched as an instant collectible to Forbes’ list of hot future collectibles and Chrysler’s forgotten AMG-built Crossfire SRT-6, another performance oddball that surfaced at auction.
The car is located in Longview, Washington, and the auction ends October 29 at 1:57 PM EDT. See the full listing and photo gallery on Cars & Bids.
