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 stylish city car mechanically identical to the VW Up and Skoda Citigo, offering impressive practicality for its size. Initially powered by a 1.0-litre three-cylinder petrol engine in 59bhp or 74bhp versions, it featured various posh special editions in collaboration with major fashion houses. From 2019, the petrol model was discontinued and replaced by the Seat Mii Electric, an 83bhp pure electric car with an official WLTP range of 161 miles. The 251-litre boot exceeds rivals like the Fiat 500 and Toyota Aygo, whilst the five-door model provides excellent access to rear seats. The interior feels solid and well-assembled, with simple, logical dashboard layout and large windows offering excellent visibility.

Whether petrol or electric, the Mii is enjoyable to drive with plenty of performance at town speeds and surprisingly good handling. The electric version delivers an 80% rapid charge in approximately 50 minutes via a 50kW charger, or a full charge in under six hours via a standard 7kW home charger. Real-world range in varied conditions reaches 130-140 miles, dropping to around 110 miles in winter. Running costs are exceptionally low; the Mii Electric costs just over £5 per full charge on standard UK tariffs, equating to 4.4p per mile. The petrol version achieves 45-50mpg, whilst insurance and servicing costs remain competitive. Parts are cheap and plentiful, making the Mii one of the most affordable cars to own and operate.

Best for: Budget-conscious buyers seeking a practical, reliable city car, those wanting an affordable pure electric vehicle, and drivers prioritising low running costs and excellent value for money.

Not ideal for: Buyers seeking the plush finish of a Fiat 500e, those wanting the most powerful engine in the city car class, or those requiring the cheapest option (Skoda Citigo offers better value).


Comparison vs Key Rivals



The Verdict

You should buy the Mii if: You're seeking a practical, reliable city car on a budget, want an affordable pure electric vehicle, or prioritise low running costs and excellent value for money.

Consider alternatives if: You desire the plush finish of a Fiat 500e, require the most powerful engine in the city car class, or need the absolute cheapest option available.

Competitive Position: The Seat Mii (2012-2021) is a seriously impressive small car that has been overshadowed by its sister cars, the cheaper Skoda Citigo and the posher VW Up. However, it remains one of the best budget runabouts available, perfectly suited to town driving whilst feeling stable enough for confident use on the open road. The later Mii Electric is a thoroughly recommendable and fun little EV, offering one of the best options for anyone seeking a budget pure electric car. Whilst it lacks the plush finish and style appeal of the Fiat 500e, it delivers impressive practicality, reliability, and affordability that few rivals can match.
