The BMW 6 SERIES COUPE (2015-18) 640I 2DR COUPE 3.0 SS 320 EU6 SE AUTO8 is a premium two-door grand tourer, positioned between executive saloons and specialist sports cars. Its smooth petrol engine and automatic gearbox deliver refined driving, while its long, low shape is distinctive on UK roads today. mycarcheck.com recorded 13 checks covering six distinct VINs, so the sample is modest but offers a snapshot. These cars averaged £17,500 in private-sale value, 52,000 miles, 5,000 miles a year and two previous keepers. These figures can frame a viewing, but each car’s condition, history and specification matter. The 640i suits drivers seeking comfort and pace for weekend trips or long journeys. It offers generous front-seat comfort, but less access and space than a four-door rival. Against coupes such as the Mercedes-Benz E-Class Coupe, it stands out for its expressive design and cruising feel. Check practicality for regular family use.
