About this car

This 2020 BMW 4 Series M Sport is advertised with 14,941 miles, approximately 29,300 below the typical mileage for its age. At £23,010, it is advertised £832 below our estimated market asking price of £23,842. To estimate its market asking price, we analyse UK dealer adverts for 1,758 BMW 4 Series cars across different ages and specifications. We first saw this car advertised 143 days ago. Its asking price has since fallen by £1,540. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 11 December 2026, and the latest recorded mileage is consistent with the advert. The seller is Big Motoring World Leeds, based in Leeds.
