About this car

This 2021 BMW 3 Series M Sport is advertised with 44,000 miles on the clock. Its asking price of £19,999 is £68 above our estimate of £19,931. 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 147 days ago, the asking price has dropped by £300. Ask the dealer why the advert shows fewer miles than the 44,701 recorded at the latest MOT. The latest recorded MOT expiry date is 23 September 2026, which has passed. Confirm its status with the dealer. It is for sale at AB Car Sales in Gunnislake.

Price and mileage comparison

Estimated market asking price: £19,931. The asking price is £68 above this estimate.

The estimate uses UK dealer asking prices, accounting for make, model, trim, version, age, mileage, fuel, gearbox, body type, driven wheels, engine size and power. It estimates an advertised price, not a confirmed sale price.

The pricing calculation includes 6,849 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 10,600 miles lower than typical for a 2021 BMW 3 Series.

Mileage concern: the advertised mileage is below the last MOT reading; ask the dealer to explain.

The recorded MOT has expired; ask the dealer for an up-to-date MOT.
