About this car

This 2021 BMW X3 M Sport is advertised with 42,000 miles, approximately 6,400 below the typical mileage for its age. Our estimated market asking price is £30,866. This car is advertised at £33,980, which is £3,114 above that figure. We use UK dealer asking prices, including 2,970 BMW X3 listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 70 days ago, the asking price has dropped by £3,000. That may be worth mentioning if you discuss the price with the dealer. You can find this car at Auto100.Co.Uk in Sutton-in-Ashfield.
