The dealer is asking £15,500, which is £2,280 below our market estimate of £17,780. We use UK dealer asking prices, including 6,764 BMW 3 Series listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 145 days ago, the asking price has dropped by £1,750. The time on sale and price change could be useful context when negotiating. Its recorded MOT is valid until 28 March 2027, and its advertised mileage is consistent with the latest MOT reading. It is advertised by Reverie Autos in Hatfield.
