The BMW 6 SERIES GRAN COUPE (2015-18) 650I 4DR GRAN COUPE 4.4 V8 SS 450 EU6 M SPORT AUTO8 is a large, four-door luxury coupé: more stylish and performance-focused than a conventional saloon, but with useful rear doors and seating. In the UK used-car market, it sits among premium executive cars, appealing to buyers wanting presence and pace rather than a practical family SUV. Mycarcheck.com recorded 47 look-ups across 19 distinct VINs, a useful snapshot rather than a complete market survey. Its checks show an average private-sale valuation of £23,600, average recorded mileage of 45,000 miles and annual mileage of 6,000. Cars had about 2.5 previous keepers on average. These figures can help set expectations, but condition, history and specification matter when comparing individual examples. Its V8 brings thrilling pace, and M Sport trim adds presence. It suits drivers wanting a grand-tourer; expect higher fuel costs than smaller-engined rivals.
