This car is advertised at £17,489, which is £285 below that figure. To estimate its market asking price, we analyse UK dealer adverts for 6,886 BMW 3 Series cars across different ages and specifications. We first recorded this advert 149 days ago, and its asking price has since fallen by £1,500. That may be worth mentioning if you discuss the price with the dealer. MOT records show an expiry date of 18 May 2027, and the latest recorded mileage is consistent with the advert. You can find this car at The Hertford Car Company in Bayford.
