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 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 and replaced by the Mii Electric, an 83bhp pure electric car with an official WLTP range of 161 miles. 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.

Whether petrol or electric, the Mii is a joy to drive with excellent handling and a surprisingly comfortable ride. Running costs are exceptionally low—the electric version costs just 4.4p per mile, roughly half that of the petrol equivalent. The Mii Electric charges to 80% in 50 minutes on a 50kW rapid charger or under six hours on a standard 7kW home charger. Insurance is affordable for the petrol, though Group 12 for the electric is higher. Servicing is inexpensive with fixed-price options available, and 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; drivers prioritising low running costs and excellent value for money.

Not ideal for: Buyers seeking premium interior finishes or badge prestige; those requiring the most powerful engine option in the city car segment; drivers needing maximum motorway performance.


Comparison vs Key Rivals



The Verdict

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

Consider alternatives if: You prioritise premium interior finishes, require maximum engine power, or need the best motorway performance in the city car segment.

Competitive Position: The Seat Mii (2012-2021) is a seriously impressive small car that has been overshadowed by its Skoda Citigo and VW Up siblings. The Skoda is cheaper, the VW is posher, but the Mii offers excellent value and style in between. The later Mii Electric is thoroughly recommendable and fun, lacking only the plush finish of the Fiat 500e but remaining one of the best budget pure electric options. The petrol version is equally recommendable—perfectly suited to town driving yet stable enough for confident open-road use. As budget runabouts go, the Seat Mii is one of the best, offering practicality, reliability, and charm at an unbeatable price.
