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.

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