The BMW 6 SERIES (2010-15) 640I 2DR COUPE 3.0 SS 320 EU6 M SPORT AUTO8 is a large, premium two-door coupe: a stylish, comfortable alternative to a saloon, rather than an everyday family hatchback or SUV. Its strong petrol engine, automatic gearbox and M Sport appearance give it a grand-touring character, suited to covering distance in comfort while still feeling lively. Mycarcheck.com has recorded 57 look-ups across 18 different VINs, so the figures offer a useful snapshot but not a full-market verdict. Checked examples average £13,700 in private-sale value and 71,000 miles, with around 6,000 miles driven yearly and about two previous keepers. These figures can help you compare an individual car, but condition, history and specification matter. Best for couples or enthusiasts, it offers style and comfort, though rear seats suit occasional use. Against the Mercedes-Benz E-Class Coupe, its sporty character and refinement stand out, but running costs are higher.
