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 city car that shares its platform with the VW Up and Skoda Citigo, making it one of the best small cars available. Initially offered with a 1.0-litre petrol engine, it was updated in 2019 to become the Mii Electric, a pure EV with an impressive official range of 161 miles. By small car standards, its practicality is excellent, with a 251-litre boot that’s larger than most rivals and enough interior space to seat four adults, particularly in the five-door version.

Whether petrol or electric, the Mii is enjoyable to drive, with nimble handling and a surprisingly comfortable ride that makes it capable beyond the city limits. Running costs are a major highlight, with petrol models achieving up to 50mpg and the Mii Electric offering significant savings on fuel. While the entry-level S trim is basic, higher specifications are well-equipped for the price. As a used purchase, the Mii represents superb value, offering a blend of practicality, efficiency, and fun driving dynamics.

Best for: Budget-conscious buyers, city drivers, those seeking a cheap-to-run first car, and anyone looking for an affordable entry into EV ownership.

Not ideal for: Buyers wanting the plushest interior (the VW Up is better), those who need a smooth automatic gearbox (the petrol auto is clunky), or drivers seeking more powerful engine options.


Comparison vs Key Rivals



The Verdict

You should buy the Mii if: You are a budget-conscious buyer looking for a cheap-to-run city car, a first-time driver, or want an affordable entry into EV ownership.

Consider alternatives if: You prioritise a plush interior, want more powerful engine options, or need a smooth automatic gearbox.

Competitive Position: The Seat Mii is a seriously impressive and recommendable small car, often unfairly overshadowed by its VW Up and Skoda Citigo siblings. It delivers fantastic practicality, low running costs, and great value, with the Mii Electric model standing out as a top choice for a budget EV. While it lacks the premium feel of some rivals, its blend of affordability and all-round competence makes it a leading contender in the city car class.
