The BMW 4 SERIES GRAN COUPE (2014-18) 420D 5DR GRAN COUPE 2.0 DPF SS 190 EU6 SPORT 6SPD is a premium five-door fastback: sleeker than a conventional family hatchback, yet more practical than a saloon. It sits in the UK’s executive-car market, combining BMW’s sporting image with everyday space and comfort. Across 169 mycarcheck.com look-ups covering 87 distinct VINs, this model has a useful market snapshot: the average recorded mileage is 90,000, with about 9,000 miles driven yearly. Checks show roughly two previous keepers on average and an average private-sale valuation of £10,900; individual cars and prices vary by condition and history. The 420d suits commuters and small families wanting comfortable long-distance travel, rear-door access and boot space, without moving to an SUV. Its diesel offers strong pulling power and respectable economy, while Sport trim adds appeal. Against Audi A5 Sportback and Mercedes CLA rivals, it stands out for practicality and enjoyable driving.
