Page 2 lists every other 2017 SEAT Mii car, cheapest first, including the 2 the groups do not pick from.

The AskCar estimate is our expected asking price for that one car, from its model, age, mileage and specification, using the 126 priced SEAT Mii adverts on AskCar as of 7 November 2026. The figures on this page describe the cars advertised, not a valuation of every 2017 SEAT Mii.

Each car: year, make, model, engine and trim, power, gearbox, fuel, body, doors, colour; mileage; price and its changes; how the price compares with the AskCar estimate; emissions standard and ULEZ compliance where it holds; MOT; dealer and town; AskCar page. Each car's AskCar page has its full price history and cheaper cars like it.
