Price and mileage comparison

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.

Advertised mileage is approximately 43,000 miles higher than typical for a 2018 Jaguar XJ.

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