About this car

This 2021 BMW Z4 M Sport has covered 29,543 miles. The dealer is asking £27,999, which is £455 below our market estimate of £28,454. To estimate its market asking price, we analyse UK dealer adverts for 496 BMW Z4 cars across different ages and specifications. We first recorded this advert 148 days ago, and its asking price has since fallen by £300. The recorded MOT expired on 29 September 2026, so ask the dealer whether it has been renewed. Our comparison with the latest MOT reading has not flagged a mileage discrepancy. It is for sale at Sandles Cars in Kings Lynn.
