SEAT is known for being competitive when it comes to servicing and the dealerships have a decent reputation for good customer service. This could help the Spanish brand pick up sales in this sector. From launch the best engine to choose is the 59bhp, 1.0-litre three-cylinder unit which should average 62.8mpg.

The cleanest engine available from launch is the 59bhp 1.0-litre. This emits 105g/km of CO2 emissions, which places it in to one of the lowest groups for car tax. If you were willing to wait a bit longer to buy a Mii then it may be worth waiting for the Ecomotive version. This model should emit 97g/km of C02 and return 67.2mpg, making it the cleanest and most economical model in the range.

Built by the VW group, the SEAT Mii should prove to be a very reliable car despite being an all-new model. The fit and finish of the materials is very good and more in keeping with larger SEAT models so should stand the test of time compared to some its cheaper-feeling rivals.
