The BMW X6 (2014-19) XDRIVE50I 5DR SUV 4.4 V8 SS 449 EU6 SE AUTO8 is a large, premium five-door SUV with a coupé-inspired shape. In the UK market it sits above mainstream family SUVs, combining imposing road presence and a luxury cabin with strong performance. Its high-powered petrol engine makes it a distinctive, less common choice than the diesel X6s often sought by long-distance drivers. mycarcheck.com has recorded five checks covering three distinct vehicles, so this is a small sample rather than a definitive picture of all X6s. Those checks show an average private-sale valuation of £21,900, average recorded mileage of 32,000, annual use of 4,000 miles and 1.2 previous keepers. Treat these figures as useful pointers, not guarantees. With all-wheel drive and an automatic, the BMW X6 suits drivers wanting a spacious car for family trips and motorway journeys, but fuel and running costs are higher than rivals.
