About this car

The estimate uses 6,724 UK dealer adverts for the BMW 3 Series, with adjustments for age, mileage, trim, engine and other specifications. Since we first spotted the advert 88 days ago, the asking price has dropped by £987. The time on sale and price change could be useful context when negotiating. MOT records show an expiry date of 9 December 2026, and the latest recorded mileage is consistent with the advert. The seller is Carbase Bristol, based in Bristol.
