About this car

This 2020 BMW 4 Series M Sport has covered 38,500 miles, around 5,200 fewer than typical for its age. At £18,490, it is advertised £51 below our estimated market asking price of £18,541. The estimate uses 1,763 UK dealer adverts for the BMW 4 Series, with adjustments for age, mileage, trim, engine and other specifications. Since we first spotted the advert 64 days ago, the asking price has dropped by £500. That may be worth mentioning if you discuss the price with the dealer. Its MOT is recorded as valid until 6 August 2027. The advertised mileage is consistent with the latest MOT reading. You can find this car at S James Prestige in Stamford.
