About this car

This 2018 BMW 3 Series M Sport has covered 73,967 miles. Our estimated market asking price is £16,058. This car is advertised at £15,607, which is £452 below that figure. Our estimate draws on 6,764 BMW 3 Series adverts across the UK, adjusting for age, mileage, trim, engine and other specifications. Since we first spotted the advert 139 days ago, the asking price has dropped by £1,479. That history is worth bearing in mind when speaking to the dealer.
