About this car

This 2021 BMW 3 Series M Sport has covered 50,488 miles, around 4,100 fewer than typical for its age. The dealer is asking £20,195, which is £1,018 above our market estimate of £19,177. Our estimate draws on 6,849 BMW 3 Series adverts across the UK, adjusting for age, mileage, trim, engine and other specifications. Since we first spotted the advert 15 days ago, the asking price has dropped by £300. MOT records show an expiry date of 23 September 2027, and the latest recorded mileage is consistent with the advert. The seller is Group 1 Hailsham BMW, based in Hailsham.
