About this car

This 2021 BMW Z4 is advertised with 44,000 miles, approximately 15,800 above the typical mileage for its age. The dealer is asking £30,500, which is £457 below our market estimate of £30,957. To estimate its market asking price, we analyse UK dealer adverts for 493 BMW Z4 cars across different ages and specifications. The asking price is now £1,250 lower than when we first recorded the advert 60 days ago. That history is worth bearing in mind when speaking to the dealer. The latest MOT record shows an expiry date of 25 May 2027, with the advertised mileage consistent with the recorded reading. It is for sale at Flat Out Cars in Cranleigh.
