The BMW 6 SERIES (2007-10) 635D 2DR COUPE 3.0D AUTO is a large, premium four-seat coupé, sitting above mainstream family cars in Britain as a stylish grand tourer rather than a practical hatchback or SUV. Its long, low shape and automatic gearbox suit buyers wanting comfort, presence and relaxed longer-distance travel. Mycarcheck.com recorded 42 look-ups for this version, spanning 13 distinct VINs. The average private-sale valuation is £5,100, with average recorded mileage of 104,000 and annual mileage of 4,000. It averages nearly six previous keepers, making a history and condition check especially worthwhile. Best suited to couples or confident drivers, it offers relaxed motorway travel and strong, smooth performance, but is less practical for families and costly to run. Against rivals such as the Mercedes-Benz CLK and Audi A5, the BMW 635d stands out with distinctive styling and a spacious, comfortable cabin, making this used coupé a special long-distance choice.
