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 2,970 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 200 miles higher than typical for a 2020 BMW X3.

The advertised mileage is consistent with the last MOT reading.
