Seat Mii (2012-2021) Pros and Cons

Pros	Cons
Impressively practical for such a small car	Misses out on more powerful engine that VW Up sister car gets
Low running costs for both petrol and electric versions	More expensive than a Skoda Citigo
Excellent value for money	Interior a little utilitarian

Quick Summary

The Seat Mii (2012-2021) is a highly regarded city car, mechanically identical to the VW Up and Skoda Citigo. Initially available with 1.0-litre petrol engines (59bhp or 74bhp), it also featured stylish special editions. From 2019, it transitioned to an 83bhp pure electric model, the Mii Electric, offering an impressive official WLTP range of 161 miles from its 36.8kWh battery, making it one of the most affordable EVs with a substantial range. The Mii was discontinued in 2021.

Despite its small footprint, the Mii is impressively practical, boasting a 251-litre boot and comfortable seating for four adults, particularly in the five-door variant. Both petrol and electric versions deliver an enjoyable driving experience with nimble handling and a surprisingly comfortable ride for a city car. Running costs are remarkably low across the range, with the Mii Electric providing significant fuel savings, and both versions benefiting from affordable insurance and servicing.

Best for: Drivers seeking an impressively practical and economical city car, buyers looking for an affordable pure electric car with a good range, and those prioritising low running costs and excellent value for money.

Not ideal for: Buyers who require a more powerful engine, those seeking the absolute cheapest option among its siblings, drivers who prefer a plush or sophisticated interior, or those needing a smooth automatic petrol gearbox.
