About this car

At 52,800 miles, this 2021 BMW X3 M Sport has covered about 4,400 more miles than other 2021 BMW X3 cars. Our estimated market asking price is £24,801. This car is advertised at £25,750, which is £949 above that figure. To estimate its market asking price, we analyse UK dealer adverts for 2,970 BMW X3 cars across different ages and specifications. We first recorded this advert 145 days ago, and its asking price has since fallen by £240. That may be worth mentioning if you discuss the price with the dealer. MOT records show an expiry date of 18 November 2026, and the latest recorded mileage is consistent with the advert. The seller is Reynolds Motor Group Southend-on-sea, based in Southend-on-SEA.
