About this car

This 2021 BMW 4 Series M Sport has covered 37,000 miles, around 5,000 fewer than typical for its age. The dealer is asking £25,850, which is £1,130 above our market estimate of £24,720. To estimate its market asking price, we analyse UK dealer adverts for 1,725 BMW 4 Series cars across different ages and specifications. Since we first spotted the advert 105 days ago, the asking price has dropped by £140. That may be worth mentioning if you discuss the price with the dealer. Its MOT is recorded as valid until 9 February 2027. The advertised mileage is consistent with the latest MOT reading. It is advertised by A & S Cars in Bishop's Stortford.
