About this car

This 2018 BMW X6 has covered 96,727 miles, around 27,500 more than typical for its age. At £19,895, it is advertised £843 above our estimated market asking price of £19,052. The estimate uses 514 UK dealer adverts for the BMW X6, with adjustments for age, mileage, trim, engine and other specifications. We first saw this car advertised 88 days ago. Its asking price has since fallen by £2,100. That history is worth bearing in mind when speaking to the dealer. The latest MOT record shows an expiry date of 27 June 2027, with the advertised mileage consistent with the recorded reading. It is for sale at Gibbons Automotive in Westbury.
