About this car

At 25,000 miles, this 2023 BMW M3 Competition has covered about 3,400 more miles than other 2023 BMW M3 cars. Our estimated market asking price is £62,108. This car is advertised at £63,000, which is £892 above that figure. To estimate its market asking price, we analyse UK dealer adverts for 777 BMW M3 cars across different ages and specifications. We first saw this car advertised 83 days ago. Its asking price has since fallen by £1,000. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 15 January 2027, and the latest recorded mileage is consistent with the advert. It is advertised by Brooklyns in Broxbourne.
