The BMW X6 (2014-19) M XDRIVE 5DR SUV 4.4 BI TURBO SS 575 EU6 AUTO8 is a high-performance luxury SUV with a coupé-like roofline. It sits near the premium end of the UK market, pairing imposing road presence and four-wheel-drive confidence with more sporting style than a conventional family SUV. mycarcheck.com has recorded 964 look-ups covering 235 distinct VINs, a useful sample of interest in this version. Checks show an average private-sale valuation of £34,800 and average recorded mileage of 51,000 miles; typically, annual use is 7,000 miles, with about three previous keepers. That combination suits buyers wanting a comfortable long-distance car with SUV practicality, rather than a commuter or family haulier. The X6 M stands out for its shape, acceleration and drive. Against rivals such as the Porsche Cayenne and Range Rover Sport, it puts sportier styling and performance first; running costs and fuel use will be substantial.
