Price and mileage comparison

Estimated market asking price: £20,154. The asking price is £96 above 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 89 adverts of this make and model across different ages and specifications.

Advertised mileage is approximately 20,500 miles higher than typical for a 2018 Tesla Model X.

Mileage concern: the advertised mileage is below the last MOT reading; ask the dealer to explain.
