The BMW 4 SERIES GRAN COUPE (2014-18) 420D 5DR GRAN COUPE 2.0 DPF SS 190 EU6 M SPORT 6SPD is a premium, five-door fastback-style hatchback: sleeker than a family hatch, with a useful tailgate and four-door practicality. It sits between mainstream hatchbacks and executive saloons in the UK used-car market, offering a sportier alternative to a conventional 3 Series. Mycarcheck.com has recorded 826 checks across 329 distinct VINs, giving a meaningful snapshot of interest. The average private-sale valuation is £11,800, with recorded mileage averaging 82,000 miles and annual use around 10,000 miles. Cars have averaged just over two previous keepers, useful context when assessing an individual example. The 420d suits commuters and small families seeking comfort, space and economy without an SUV. M Sport adds a sharper look and lively drive. Its hatchback access distinguishes it from the Audi A5 Sportback and Mercedes-Benz CLA, though the sloping roof limits headroom.
