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. Initially offered with a 1.0-litre three-cylinder petrol engine in 59bhp or 74bhp versions, it delivers nippy, light-footed driving dynamics ideal for town use. From 2019, the petrol model was discontinued, replaced by the Seat Mii Electric with 83bhp and an official WLTP range of 161 miles. The 251-litre boot is impressively spacious for its class, and the five-door model provides excellent access. The interior feels solid and well-appointed, though less plush than the VW Up. A 2016 facelift introduced the sportier FR Line with stiffer suspension and generous equipment levels.

Whether petrol or electric, the Mii is a pleasure to drive with eager handling and a surprisingly comfortable ride suitable for both town and open-road use. The Mii Electric offers exceptional value as one of the cheapest electric cars available, with real-world range of 130-140 miles in varied conditions. Running costs are exceptionally low: petrol versions achieve 45-50mpg, whilst the electric model costs just 4.4p per mile on standard tariffs. Insurance is affordable, servicing costs are competitive, and parts are cheap and plentiful. Avoid the automatic petrol version, which features a slow-shifting, clunky gearbox unsuitable for this otherwise nimble car.

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 a more powerful petrol engine, those wanting premium interior finishes, or drivers requiring the cheapest option in the city car segment (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 require a more powerful petrol engine, desire premium interior finishes, or need the absolute cheapest option in the city car segment.

Competitive Position: The Seat Mii (2012-2021) is an impressive small car that has been overshadowed by its sister cars, the cheaper Skoda Citigo and the posher VW Up. However, it remains a seriously recommendable option, particularly the later Mii Electric, which offers one of the best budget pure electric car experiences available. The petrol version is equally compelling, delivering town-focused practicality with confident open-road capability. With its spacious interior, low running costs, reliability, and cute styling, the Seat Mii represents one of the best budget runabouts on the used market, offering genuine value where rivals like the Fiat 500 prioritise style and the Toyota Aygo focuses on affordability.
