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 that's mechanically identical to the VW Up and Skoda Citigo. Available with a 1.0-litre petrol engine in 59bhp or 74bhp versions, it offers impressive practicality with a 251-litre boot and comfortable seating for four. From 2019, the petrol model was discontinued, replaced by the Mii Electric with an 83bhp motor and 161-mile WLTP range. The electric version proved popular as one of the cheapest EVs available, with a 36.8kWh battery offering longer range than the Fiat 500e, Honda e, and Mini Electric. Avoid the automatic petrol variant, which features a slow-shifting, clunky gearbox unsuitable for this otherwise nippy car.

Both petrol and electric versions deliver excellent value and practicality. The petrol Mii achieves 45-50mpg, whilst the electric model costs just over £5 per full charge on standard UK tariffs. Running costs are among the lowest available, with cheap insurance, affordable servicing, and plentiful, inexpensive parts. The Mii handles eagerly in corners with a surprisingly comfortable ride, making it suitable for town driving and confident motorway use. Though overshadowed by the cheaper Skoda Citigo and posher VW Up, the Seat Mii remains a seriously impressive small car and thoroughly recommendable budget runabout.

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

Not ideal for: Buyers prioritising maximum power, premium interior finishes, or those seeking the cheapest option in this segment (Skoda Citigo offers better value).


Comparison vs Key Rivals



The Verdict

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

Consider alternatives if: You prioritise maximum power, premium interior finishes, or require the cheapest option in this segment (Skoda Citigo offers better value).

Competitive Position: The Seat Mii (2012-2021) is a seriously impressive small car that has been overshadowed by its mechanically identical siblings—the cheaper Skoda Citigo and posher VW Up. However, it remains thoroughly recommendable as a budget runabout offering excellent practicality, low running costs, and genuine value for money. The Mii Electric is particularly compelling for budget-conscious EV buyers, delivering impressive range and charging flexibility at an affordable price point. Whilst it lacks the plush finish of the Fiat 500e, it outperforms many rivals in real-world capability. Both petrol and electric versions are perfectly suited to town driving yet stable enough for confident motorway use, making the Seat Mii an outstanding choice for practical, economical motoring.
