About this car

The estimate uses 128 UK dealer adverts for the BMW X3 M, with adjustments for age, mileage, trim, engine and other specifications. Since we first spotted the advert 99 days ago, the asking price has dropped by £3,000. The time on sale and price change could be useful context when negotiating. MOT records show an expiry date of 30 June 2027, and the latest recorded mileage is consistent with the advert. The seller is Arnold Clark Manchester Vauxhall, based in Manchester.
