The BMW 6 Series (2004-07) 650i 2dr Coupe 4.8 SMG Auto is a premium two-door coupe, offering a stylish, comfortable alternative to a luxury saloon rather than a practical family hatchback or SUV. In the UK used-car market, it occupies a specialist, relatively affordable corner of grand touring cars. It suits drivers seeking long-distance comfort and an engaging drive, especially couples or enthusiasts who need neither easy rear-seat access nor low running costs. Its 4.8-litre V8 and distinctive styling give it more presence than many executive cars, while the automated gear-changing system adds a distinctive character. Mycarcheck.com recorded 22 look-ups across nine VINs, a modest sample. Checks show a private-sale value averaging £4,000, mileage of 95,000, 3.8 previous keepers and annual mileage of 3,000. Against rivals such as the Mercedes-Benz CLK and Jaguar XK, this BMW is known for its V8 character, though buyers should budget for fuel and upkeep.
