The BMW 6 SERIES GRAN COUPE (2011-15) 640D 4DR GRAN COUPE 3.0 DPF SS 313 EU5 M SPORT AUTO8 is a premium four-door coupé: sleeker than a saloon, yet with rear doors and useful boot. In the UK market, it sits among stylish executive cars, offering a dramatic alternative to family saloons. Mycarcheck.com has recorded 4,705 checks covering 1,519 VINs, a substantial sample of interest in this model. Its observed cars average around £13,000, 87,000 miles and 8,000 miles a year, with about 3.6 previous keepers. These figures are useful context, not a guarantee for any car. The powerful diesel and smooth automatic make the 640d well suited to long-distance commuting and motorway trips; it can serve a family wanting comfort and style, though its size and running costs suit experienced buyers better than new drivers. Against the Audi A7 and Mercedes-Benz CLS, its blend of pace, refinement and practicality stands out.
