About this car

This 2021 BMW 3 Series M Sport has covered 25,955 miles, around 28,600 fewer than typical for its age. Its asking price of £22,450 is £763 below our estimate of £23,213. We use UK dealer asking prices, including 6,849 BMW 3 Series listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 43 days ago, the asking price has dropped by £500. The recorded MOT expired on 5 September 2026, so ask the dealer whether it has been renewed. Our comparison with the latest MOT reading has not flagged a mileage discrepancy. The seller is AJC Car Sales, based in Benton.
