The dealer is asking £39,995, which is £4,078 below our market estimate of £44,073. To estimate its market asking price, we analyse UK dealer adverts for 775 BMW M3 cars across different ages and specifications. We first recorded this advert 75 days ago, and its asking price has since fallen by £3,000. That history is worth bearing in mind when speaking to the dealer.
