This 2023 example is a low-mileage, loaded coupe in striking Portimao Blue, and it still carries a BMW Certified Pre-Owned warranty. It is on Cars and Bids at $27,777 with four days to go.2023 BMW M850i xDrive Cars & BidsWhat it's worth right nowThe M850i has depreciated steadily from its lofty sticker, making it a lot of car for the money. According to Edmunds and current listings, clean low-mileage 2023 coupes generally trade from around $55,000 into the high $60,000s, with certified examples reaching into the low $70,000s, against a sticker of roughly $108,000 when new.AdvertisementAdvertisementThis car's low mileage, loaded specification, and transferable warranty support that range. The loan payoff and the notes below are the main things to weigh. At $27,777 with four days remaining and a reserve, the bidding is early and should climb into the high $50,000s.2023 BMW M850i xDrive Cars & BidsCondition and detailsThe car is a well-kept, well-optioned example. Finished in Portimao Blue Metallic over an Ivory and blue interior, it carries the M Sport Professional, M Performance, and Driving Assistance packages, adaptive M suspension Pro, an M Carbon roof, and carbon-fiber interior trim, with the twin-turbocharged 4.4-liter V8 sending 523 horsepower through the eight-speed automatic and xDrive all-wheel drive.2023 BMW M850i xDrive Cars & BidsIt has been ceramic coated and tinted, and importantly, it carries a BMW Certified Pre-Owned warranty valid until June 2027 that transfers to the buyer for a nominal fee. A few points to note. There is a loan on the car, so the payoff must be coordinated, and the title may only be available afterward. The car has the Driving Assistance Package but not the Professional version, so it lacks adaptive cruise control, which a bidder confirmed.2023 BMW M850i xDrive Cars & BidsCosmetically, there are some chips and scratches, front-lip scuffs, and a scratched front wheel. The twin-turbo N63 V8 rewards diligent maintenance, so the remaining CPO coverage is a genuine asset, though a pre-purchase inspection is still wise.2023 BMW M850i xDrive Cars & BidsAdvertisementAdvertisementThe offerSpecificationDetailMakeBMWModelM850i xDrive CoupeYear2023Mileage26,400 milesEngineTwin-turbocharged 4.4-liter V8Power523 hp and 553 lb.ft of torqueTransmission8-speed automaticDrive typeAll-wheel driveExterior colorPortimao Blue MetallicInterior colorIvory and blueCurrent bid$27,777, with four days leftInterested in this 2023 BMW M850i xDrive Coupe? View the listing here.What makes the M850i uniqueThe 8 Series is BMW's grand-touring flagship, revived in 2019 after nearly two decades to sit above the entire range as the marque's most luxurious two-door. The M850i is its performance pinnacle short of the full M8, with a twin-turbocharged 4.4-liter V8 producing 523 horsepower, xDrive all-wheel drive for all-weather traction, and adaptive suspension that lets it shift from serene cruiser to genuinely quick GT. Car and Driver clocked the M850i to 60 mph in the low three-second range, supercar territory, yet it seats four in hushed luxury.2023 BMW M850i xDrive Cars & BidsThat blend of long, sweeping styling, effortless V8 performance, and cutting-edge luxury technology is what makes the M850i so appealing, especially now that depreciation has brought it within reach. It delivers the presence and pace of a much more expensive car for a fraction of its original price.My takeFor the money, this is a lot of luxury and performance in a genuinely striking package. The M850i is a superb high-speed GT, and this one's low mileage, loaded specification, and Portimao Blue paint make it especially appealing, with the remaining CPO warranty taking much of the risk out of buying a complex German V8 coupe. That warranty is the differentiator here.AdvertisementAdvertisementFair value sits in the $52,000 to $66,000 range, most likely around $56,000 to $62,000, so the early bidding has room to climb. Before bidding, coordinate the loan payoff, confirm the warranty transfer, and factor in the missing adaptive cruise if that matters to you. Handle that, and you own a fast, luxurious, warrantied flagship coupe for well under half its original cost.Disclaimer: This post is for informational purposes only.
