About this car

With 50,631 miles on the clock, this 2021 BMW 3 Series M Sport has done roughly 4,000 fewer miles than a typical 2021 BMW 3 Series. Our estimated market asking price is £22,747. This car is advertised at £22,390, which is £357 below that figure. The estimate uses 6,849 UK dealer adverts for the BMW 3 Series, with adjustments for age, mileage, trim, engine and other specifications. We first saw this car advertised 70 days ago. Its asking price has since fallen by £510. The time on sale and price change could be useful context when negotiating. MOT records show an expiry date of 29 June 2027, and the latest recorded mileage is consistent with the advert. The seller is MINI UK at Stratstone Hull, based in Hull.
