About this car

At 34,868 miles, this 2021 BMW 4 Series M Sport has covered about 7,100 fewer miles than other 2021 BMW 4 Series cars. Our estimated market asking price is £26,203. This car is advertised at £24,990, which is £1,213 below that figure. We use UK dealer asking prices, including 1,763 BMW 4 Series listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 102 days ago, the asking price has dropped by £3,000. That may be worth mentioning if you discuss the price with the dealer. MOT records show an expiry date of 22 December 2026, and the latest recorded mileage is consistent with the advert. The seller is Williams Bmw Rochdale, based in Rochdale.
