About this car

With 51,676 miles on the clock, this 2021 BMW 4 Series M Sport Pro Edition has done roughly 9,800 more miles than a typical 2021 BMW 4 Series. At £24,250, it is advertised £807 below our estimated market asking price of £25,057. The estimate uses 1,756 UK dealer adverts for the BMW 4 Series, with adjustments for age, mileage, trim, engine and other specifications. We first saw this car advertised 82 days ago. Its asking price has since fallen by £2,850. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 18 May 2027, and the latest recorded mileage is consistent with the advert. You can find this car at Car Planet Watford in Rickmansworth.
