About this car

The advertised mileage for this 2023 BMW M3 Competition is 23,333 miles. Our estimated market asking price is £59,369. This car is advertised at £57,990, which is £1,379 below that figure. The estimate uses 775 UK dealer adverts for the BMW M3, with adjustments for age, mileage, trim, engine and other specifications. We first saw this car advertised 102 days ago. Its asking price has since fallen by £4,000. That may be worth mentioning if you discuss the price with the dealer. MOT records show an expiry date of 29 June 2027, and the latest recorded mileage is consistent with the advert. The seller is Stratstone Bmw Chesterfield, based in Chesterfield.
