About this car

This 2021 BMW M4 Competition has covered 35,000 miles. Our estimated market asking price is £45,999. This car is advertised at £44,995, which is £1,004 below that figure. We use UK dealer asking prices, including 732 BMW M4 listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 61 days ago, the asking price has dropped by £1,000. That history is worth bearing in mind when speaking to the dealer. Its MOT is recorded as valid until 10 April 2027. The advertised mileage is consistent with the latest MOT reading. It is for sale at AH Specialist Cars in Watford.
