About this car

The advertised mileage for this 2021 BMW 3 Series M Sport is 54,688 miles. Its asking price of £22,500 is £1,405 above our estimate of £21,095. To estimate its market asking price, we analyse UK dealer adverts for 6,849 BMW 3 Series cars across different ages and specifications. Since we first spotted the advert 134 days ago, the asking price has dropped by £500. The time on sale and price change could be useful context when negotiating. MOT records show an expiry date of 14 December 2026, and the latest recorded mileage is consistent with the advert. You can find this car at Colin Ludwell Cars in Bristol.
