The BMW 6 SERIES (2010-15) 640I 2DR COUPE 3.0 SS 320 EU6 SE AUTO8 is a two-door grand tourer: more stylish and luxurious than a family hatchback, and aimed at buyers seeking a special-feeling car. Its six-cylinder petrol engine and automatic gearbox deliver smooth, strong performance, while the low shape gives it road presence. mycarcheck.com has recorded just two checks, covering two distinct cars, so these figures are a small snapshot, not a market-wide picture. Within that sample, average private-sale value was £11,000, mileage averaged 61,000 miles, and annual mileage averaged 5,000. These numbers may help frame a car, but condition and history matter more. It suits couples or enthusiasts wanting long journeys and performance, rather than buyers needing rear-seat access or low running costs. Compared with the Mercedes-Benz E-Class Coupe and Audi A7, the 640i is known for its engaging drive and luxurious comfort. Check history and condition carefully.
