BMW 6 SERIES GRAN COUPE (2011-15) 640I 4DR GRAN COUPE 3.0 SS 320 EU6 M SPORT AUTO8 is a four-door coupe: an alternative to an executive saloon, sitting near the top end of the UK used-car market. This 2011–15 640i M Sport pairs a smooth petrol engine with an automatic gearbox, blending long-distance comfort with a dramatic, sporty appearance. Mycarcheck.com recorded 105 checks across 12 distinct VINs, giving a useful snapshot rather than a full picture of every car. The average recorded mileage was 61,000, with about 5,000 miles driven annually; the average private-sale valuation was £15,000. Checks showed an average of 5.8 previous keepers, so review each car’s history carefully. Suited to commuters and motorway drivers, it offers space but is less practical than a family hatchback. Styling and M Sport trim distinguish it from the Mercedes-Benz CLS and Audi A7; performance is enjoyable, though running costs are higher.
