About this car

We use UK dealer asking prices, including 2,129 SEAT Leon listings, and account for the car’s age, mileage and specification. Since we first spotted the advert 148 days ago, the asking price has dropped by £1,300. That may be worth mentioning if you discuss the price with the dealer. MOT records show an expiry date of 13 March 2027, and the latest recorded mileage is consistent with the advert. It is for sale at Available Car Supermarket - Castle Donington in Castle Donnington.
