About this car

At £21,150, it is advertised £2,885 below our estimated market asking price of £24,035. The estimate uses 493 UK dealer adverts for the BMW Z4, with adjustments for age, mileage, trim, engine and other specifications. We first saw this car advertised 62 days ago. Its asking price has since fallen by £2,350. That history is worth bearing in mind when speaking to the dealer. Its recorded MOT is valid until 27 February 2027, and its advertised mileage is consistent with the latest MOT reading. The seller is Car Planet Watford, based in Rickmansworth.
