About this car

This 2018 SEAT Mii has covered 103,617 miles, around 60,000 more than typical for its age. Our estimated market asking price is £4,028. This car is advertised at £3,950, which is £78 below that figure. Our estimate draws on 126 SEAT Mii adverts across the UK, adjusting for age, mileage, trim, engine and other specifications. Since we first spotted the advert 85 days ago, the asking price has dropped by £300. That may be worth mentioning if you discuss the price with the dealer. MOT records show an expiry date of 27 April 2027, and the latest recorded mileage is consistent with the advert. You can find this car at Orchard Automotive Group in Gillingham.
