The BMW 6 SERIES (2004-07) 650I 2DR COUPE 4.8 SPORT is a large, two-door luxury coupé, sitting above everyday BMW saloons as a stylish, powerful grand-tourer rather than a practical family hatchback. Its long, low shape and V8 character make it distinctive, while limited rear access and space suit occasional passengers. mycarcheck.com has recorded 18 look-ups covering seven different VINs, a modest sample that offers a useful snapshot rather than a full market picture. Those checks show an average private-sale valuation of £2,600 and average recorded mileage of 118,000 miles. The average annual mileage is just 1,000 miles, and cars have had almost seven previous keepers on average, so condition and history deserve careful attention. It suits buyers wanting comfortable, swift long-distance travel and a special weekend car, not low-cost commuting. Against Mercedes-Benz and Jaguar coupés, it offers a bold, driver-focused alternative; inspect maintenance records before buying in this class.
