About this car

With 45,404 miles on the clock, this 2021 BMW 1 Series has done roughly 2,800 more miles than a typical 2021 BMW 1 Series. Our estimated market asking price is £22,736. This car is advertised at £20,990, which is £1,746 below that figure. We use UK dealer asking prices, including 7,028 BMW 1 Series listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 21 days ago, the asking price has dropped by £510. The recorded MOT expired on 10 October 2026, so ask the dealer whether it has been renewed. Our comparison with the latest MOT reading has not flagged a mileage discrepancy. It is for sale at FRF Volvo in Swansea.
