It failed its MOT on 23 September 2025 (offside rear tyre has a cut in excess of the requirements deep enough to reach the ply or cords) and passed 7 days later, on 30 September 2025.

Advisories at the latest test: nearside front tyre has a cut but not deep enough to reach the ply or cords outer wall.

Mileage at that test: 65,852 miles, which matches the advertised 70,000 miles.

Advertised mileage is about 20,100 miles higher than the median mileage of a 2020 BMW X6 on AskCar.
