The BMW X4 (2018-22) M40I XDRIVE 5DR SUV 3.0 354 GPF SS EU6 AUTO8 is a premium five-door SUV with a coupe-inspired sloping roof. It sits between practical family SUVs and sleeker, sportier models in the UK market, offering a distinctive alternative to the BMW X3 and rivals such as the Mercedes-Benz GLC Coupe. mycarcheck.com records show strong interest: the model has generated 1,057 checks covering 414 different VINs. In those checks, average private-sale value was £35,700, average recorded mileage 37,000 miles, and cars had around 1.4 previous keepers. Typical annual mileage was 8,000, useful context when assessing a used example. The M40i suits drivers wanting brisk performance and all-weather grip, while retaining room for passengers and everyday luggage. Its bold styling and engaging drive make it more exciting than a conventional SUV, though the sloping roof and running costs may suit couples or smaller families better than space-first buyers.
