The BMW 6 SERIES GRAN COUPE (2011-15) M6 4DR GRAN COUPE 4.4 V8 SS 560 EU6 DCT AUTO7 is a high-performance, four-door luxury coupé: sleeker than a conventional saloon, but with useful rear doors and a spacious boot. In the UK used market, it sits near the top of the executive-car class, offering rare supercar-like pace in an elegant, everyday shape. Mycarcheck.com recorded 384 checks covering 81 distinct VINs, a useful snapshot of interest in this rare M6. Checks show an average private-sale valuation of £22,100, average recorded mileage of 58,000 and annual mileage of 5,000; cars had about four previous keepers on average. These figures describe checked examples, not a guarantee for any individual car. Ideal for drivers wanting a cruiser with passenger space, it is less suited to budget commuters. Against the CLS and A7, the M6 offers thrilling performance, elegant styling and premium comfort, but costs more.
