The BMW X4 (2021-25) is a premium mid-size SUV with a sloping, coupe-like roof, aimed at buyers who want SUV practicality with a sportier look. It sits above mainstream family SUVs in the UK market and shares much with the more upright BMW X3, while its shape gives it a distinctive, less conventional presence. mycarcheck.com records 1,999 checks covering 1,039 different VINs, a substantial sample. The cars checked averaged £47,100 in private-sale value and 30,000 miles, with annual mileage of 9,000. Their average keeper count was about 0.6, suggesting many checked examples had had few owners; figures describe checked cars, not every X4. It suits commuters and small families wanting a premium everyday car, though the sloping roof is less practical than the X3’s. Its engaging drive and upscale cabin stand out. Against the Mercedes-Benz GLC Coupé and Audi Q5 Sportback, the BMW X4 is a sporty, style-led, distinctive alternative.
