The BMW 4 Series Gran Coupe is a premium five-door car with a sleek, coupé-inspired shape and a useful hatchback-style boot. This 420d SE Business Media Auto8 pairs a 2.0-litre diesel with an automatic gearbox, offering a more stylish, engaging alternative to family hatchbacks and saloons for UK buyers. Mycarcheck.com records 109 look-ups covering 15 distinct VINs, though not the whole market. Across those checks, the reported average private-sale valuation was £9,300, recorded mileage averaged 100,000 miles, and annual mileage 6,000 miles. Cars had roughly 3.3 previous keepers, so check each car’s history carefully. The 420d Gran Coupe suits commuters and small families wanting comfortable long-distance transport without the bulk of an SUV. Its diesel engine and eight-speed automatic are appealing for motorway journeys, while the wide-opening rear hatch adds practicality. Against the Audi A5 Sportback and rivals, it stands out for its styling and BMW’s driver-focused feel.
