About this car

This car is advertised at £51,995, which is £266 below that figure. To estimate its market asking price, we analyse UK dealer adverts for 747 BMW M3 cars across different ages and specifications. The asking price is now £1,000 lower than when we first recorded the advert 146 days ago. That may be worth mentioning if you discuss the price with the dealer. MOT records show an expiry date of 10 February 2027, and the latest recorded mileage is consistent with the advert. It is for sale at Brook Cars Company in Telford.
