About this car

This 2021 BMW 4 Series M Sport is advertised with 93,379 miles, approximately 52,700 above the typical mileage for its age. At £18,900, it is advertised £1,464 above our estimated market asking price of £17,436. The estimate uses 1,758 UK dealer adverts for the BMW 4 Series, with adjustments for age, mileage, trim, engine and other specifications. Since we first spotted the advert 148 days ago, the asking price has dropped by £2,000. The time on sale and price change could be useful context when negotiating. MOT records show an expiry date of 18 March 2027, and the latest recorded mileage is consistent with the advert. The seller is Sytner Select Cardiff, based in Cardiff.
