About this car

This 2023 BMW M3 Competition has covered 47,461 miles, around 25,400 more than typical for its age. Our estimated market asking price is £51,506. This car is advertised at £54,995, which is £3,489 above that figure. We use UK dealer asking prices, including 775 BMW M3 listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 104 days ago, the asking price has dropped by £9,000. That may be worth mentioning if you discuss the price with the dealer. It is advertised by Agnew Group Bavarian BMW in Belfast.
