SEAT Mii review - Practicality, comfort and boot space

A spacious interior can fool you into thinking the SEAT Mii is in the next class up

SEAT has made good use of space with the Mii and overall, it's a surprisingly practical little hatchback in either three- or five-door guise. 

Although it measures just three-and-a-half meters long, the Mii is far more practical than similarly sized rivals such as the Fiat 500, and at times, feels as big as cars in the class above such as the Volkswagen Polo.

All models in the Mii range get practical touches such as big storage bins in the doors for water bottles or other personal items, and the Mii’s evident build quality and refinement helps make it comfortable on long journeys too. 


At 3,557mm long, 1,641mm wide and 1,478mm tall, the Mii shares its boxy profile with its sister cars from the VW Group stable. It’s a little shorter than the Hyundai i10 and Fiat Panda, which are 3,665mm long and 3,653mm respectively, but a shade longer than the 3,466mm Citroen C1.

Leg room, head room & passenger space 

Most city cars end up with their rear seats being used as a dumping ground for shopping – and the modest boots on offer here demonstrate why – but if you do need to get people into the back of the Mii, they’ll be more comfortable than some rivals. Then again, if you regularly do need to go four up, you’d be better served looking for a monthly deal on a cheap supermini than a relatively high-end version of a city car.

Four adults can easily sit in comfort in the Mii, where passengers and the driver alike get excellent visibility and headroom. That said, it is still a city car so legroom isn’t the greatest in the back seats, which are far more suited to children.

The five-door model obviously makes getting into the back easier than the three-door variant, but it's a shame that rear passengers have to make do with pop-out windows.

ISOFIX child seat mounts with top tethers are standard on the rear seats.


The Mii's boot space is also a big plus, and the 251-litre boot can be expanded to create a cave-like 951-litre load area, which is considerably more than the Fiat 500's 185 and 550 litres.

All versions of the Mii gets a clever double-layered floor, which means you can choose between extra capacity or a flat loading bay. 60:40 split rear seats are standard across the range, too.
