The BMW 6 SERIES GRAN TURISMO (2017-21) is a premium five-door hatchback blending executive-car comfort with a roomy cabin. It sits between saloons and SUVs in the UK used-car market: sleeker than an SUV, yet more practical than many luxury saloons, with a generous boot and easy access for passengers. mycarcheck.com recorded 2,934 look-ups across 1,292 different VINs, a substantial sample. Checked cars average £22,700 in private-sale value, 55,000 miles and about 12,000 miles driven yearly. Owners average around 1.46 previous keepers, suggesting many examples have had one or two owners; condition and service history still matter when buying used. Best for families and frequent commuters, the 6 Series Gran Turismo offers long-distance comfort without the bulk of an SUV. Spacious rear seats, a refined ride and sweeping liftback design make it distinctive. It rivals the Audi A7 and Mercedes-Benz CLS, appealing to buyers who value comfort and everyday practicality.
