About this car

This 2020 BMW X6 M Sport is advertised with 51,000 miles on the clock. At £33,975, it is advertised £3,088 below our estimated market asking price of £37,063. We use UK dealer asking prices, including 523 BMW X6 listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 148 days ago, the asking price has dropped by £2,000. That history is worth bearing in mind when speaking to the dealer. MOT records show an expiry date of 14 February 2027, and the latest recorded mileage is consistent with the advert. It is for sale at PCBS Sales in Tonbridge.

Price and mileage comparison

Estimated market asking price: £37,063. The asking price is £3,088 below 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 523 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 1,300 miles higher than typical for a 2020 BMW X6.

The advertised mileage is consistent with the last MOT reading.
