The BMW 6 SERIES GRAN COUPE (2015-18) 650I 4DR GRAN COUPE 4.4 V8 SS 450 EU6 SPORT AUTO8 is a large, premium four-door coupe: sleeker than a conventional executive saloon, with room for four adults and a useful boot. In the UK it sits near the luxury end of the market, aimed at buyers wanting presence and comfort. Mycarcheck.com has recorded six checks across one distinct VIN, so this is a small sample rather than a market-wide picture. Those checks show an average private-sale valuation of £21,600, around 49,000 miles, 11,000 miles a year and one previous keeper. It suits experienced drivers, couples or families seeking a refined long-distance car, rather than a low-cost commuter. Its V8 delivers effortless acceleration and an engaging drive; sweeping styling and a plush cabin distinguish it from rivals such as the Mercedes-Benz CLS and Audi A7. It prioritises luxury over low running costs overall.
