About this car

To estimate its market asking price, we analyse UK dealer adverts for 3,009 BMW X3 cars across different ages and specifications. The asking price is now £2,250 lower than when we first recorded the advert 93 days ago. That may be worth mentioning if you discuss the price with the dealer. The latest MOT record shows an expiry date of 5 February 2027, with the advertised mileage consistent with the recorded reading. You can find this car at Car Planet Watford in Rickmansworth.
