About this car

This 2021 BMW Z4 M Sport has covered 30,801 miles, around 2,600 more than typical for its age. The dealer is asking £27,700, which is £612 below our market estimate of £28,312. To estimate its market asking price, we analyse UK dealer adverts for 493 BMW Z4 cars across different ages and specifications. We first recorded this advert 64 days ago, and its asking price has since fallen by £1,800. The time on sale and price change could be useful context when negotiating. MOT records show an expiry date of 19 August 2027, and the latest recorded mileage is consistent with the advert. It is advertised by Saxtons.co.uk in Chelmsford.
