The BMW 4 SERIES GRAN COUPE (2017-21) 420I XDRIVE 5DR GRAN COUPE 2.0 SS 184 EU6 SPORT 6SPD is a premium, five-door fastback-style family car: sleeker than a conventional hatchback, but more practical than a two-door coupe. In the UK, it sits between mainstream family cars and pricier executive saloons, appealing to buyers wanting style without losing everyday usefulness. It suits commuters, couples and small families who need rear doors and a useful boot, while its all-wheel drive brings extra confidence in wet or slippery conditions. The 2.0-litre petrol engine offers brisk, composed progress, and Sport trim gives the cabin a more purposeful feel. It is a more stylish alternative to an Audi A5 Sportback or Mercedes-Benz C-Class, though running costs can exceed those of ordinary family hatchbacks. Mycarcheck's small sample (five checks, four VINs) gives a £13,900 average private-sale valuation, 38,000 miles, 11,000 annual miles and 0.8 previous keepers.
