About this car

At 85,003 miles, this 2021 BMW 3 Series M Sport has covered about 30,500 more miles than other 2021 BMW 3 Series cars. Our estimated market asking price is £15,491. This car is advertised at £15,450, which is £41 below that figure. The estimate uses 6,811 UK dealer adverts for the BMW 3 Series, with adjustments for age, mileage, trim, engine and other specifications. We first saw this car advertised 146 days ago. Its asking price has since fallen by £500. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 6 May 2027, and the latest recorded mileage is consistent with the advert. The seller is Heartys of Peterborough, based in Peterborough.
