About this car

This 2023 BMW Z4 has covered 41,000 miles. The dealer is asking £37,450, which is £1,509 above our market estimate of £35,941. Our estimate draws on 494 BMW Z4 adverts across the UK, adjusting for age, mileage, trim, engine and other specifications. Since we first spotted the advert 19 days ago, the asking price has dropped by £500. Ask the dealer why the advert shows fewer miles than the 41,628 recorded at the latest MOT. Its recorded MOT is valid until 31 August 2027. The seller is Boss Motor Company, based in Chesham.

How we estimate prices and check cars

Price and mileage comparison

Estimated market asking price: £35,941. The asking price is £1,509 above this estimate.

The estimate uses UK dealer asking prices, accounting for make, model, trim, version, age, mileage, fuel, gearbox, body type, driven wheels, engine size and power. It estimates an advertised price, not a confirmed sale price.

The pricing calculation includes 494 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 22,600 miles higher than typical for a 2023 BMW Z4.

Mileage concern: the advertised mileage is below the last MOT reading; ask the dealer to explain.
