The BMW 6 SERIES COUPE (2015-18) 640D 2DR COUPE 3.0 DPF SS 313 EU6 M SPORT LIMITED EDITION AUTO8 is a premium two-door grand tourer, but less practical than a family hatchback or SUV. In the UK, it sits in the executive-coupe market, appealing to buyers wanting comfort, presence and long-distance ability. mycarcheck.com records 18 lookups covering just three distinct VINs, so the figures are useful context rather than a large market sample. Across those checks, average recorded mileage was 54,000, annual mileage 10,000, and previous keepers 2.5; average private-sale valuation was £21,700. The 640d suits couples, professionals and motorway drivers seeking comfort and strong performance, rather than rear-seat access or low running costs. Its elegant premium coupe shape, sporty M Sport styling and smooth automatic gearbox create a memorable drive. Against rivals such as the Mercedes-Benz E-Class Coupe, it is known for effortless pace and comfort on long journeys and style.
