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. Initially offered with 1.0-litre petrol engines in 59bhp or 74bhp versions, it delivers impressive practicality with a 251-litre boot and comfortable seating for four. From 2019, the petrol model was discontinued, replaced by the Seat Mii Electric with an 83bhp motor and 161-mile WLTP range. The electric version proved popular as one of the cheapest EVs available, offering longer range than the Fiat 500e, Honda e, and Mini Electric despite its modest 36.8kWh battery.

Both petrol and electric versions are excellent to drive, with eager handling and a surprisingly comfortable ride suitable for town and open-road use. Running costs are exceptionally low: the electric model costs just 4.4p per mile on standard tariffs, whilst the petrol achieves 45-50mpg. Insurance, servicing, and parts are all affordable. The Mii Electric features heated front seats, cruise control, air conditioning, and lane keep assist as standard. Avoid the automatic petrol version and basic S trim without air conditioning. The Mii was discontinued in 2021 with no direct replacement.

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

Not ideal for: Buyers seeking premium interior finishes, those wanting the most powerful engine option, or those preferring the cheaper Skoda Citigo or plusher VW Up.


Comparison vs Key Rivals



The Verdict

You should buy the Mii if: You're on a tight budget, seeking a practical and reliable city car, or interested in an affordable pure electric vehicle with genuine range capability.

Consider alternatives if: You prioritise premium interior finishes, require the most powerful engine option, or prefer the cheaper Skoda Citigo or plusher VW Up.

Competitive Position: The Seat Mii (2012-2021) is an impressive small car that has been overshadowed by its sister cars, the Skoda Citigo and VW Up. Whilst the Skoda offers better value and the VW provides a plusher feel, the Mii strikes an excellent balance between affordability and quality. The Mii Electric is particularly recommendable as a budget-friendly pure electric option, offering longer range than the Fiat 500e, Honda e, and Mini Electric. A used petrol Mii is equally compelling, delivering practicality, reliability, and charm at an unbeatable price. As budget runabouts go, the Seat Mii is one of the best available.
