Impressive comfort and refinement make this a very sophisticated city car
All the controls are simple to use

Solid feel should give you confidence over reliability
As good as it gets for city cars
Avoid entry-level car, and you'll have no complaints
You can choose from two 1.0-litre, three-cylinder petrol engines, one with 59bhp and the other with 74bhp. The lower-powered engine is brisk enough for town driving, but if you regularly venture onto faster roads, you're better off with the stronger engine. The engines are smooth and quiet, and only at low revs can you feel any vibration through the pedals.
The ride is wonderfully supple, and the light but responsive steering is ideal for manoeuvres around town and parking in tight spaces. Decent body control and a neat gearchange mean the Mii is fun to drive, too.
Very little road noise can be heard in the cabin, but there's a bit too much wind noise at motorway speeds.
The dashboard is simple, smart and easy to use, with all of the major controls being well placed and well marked. The interior has good quality overall, though a few unappealing, hard plastics prevent it from feeling as classy as its sister car, the VW Up. SE and Sport trims get a glossy top to the dash, along with some chrome highlights, which help to smarten things up.
The driving position is good, and it's easy to get comfortable even though the steering wheel doesn't have reach adjustment.
The front seats are impressively spacious, and there's plenty of room for adults in the back, too. The Mii's boot is larger than most rival city cars', and you can fold down the rear seats to expand the load area. Bear in mind, though, that the high boot lip can make it tricky to load heavy items.
Entry-level S models include and MP3 socket and four airbags, while Ecomotive adds air-con, electric front windows, remote central locking and a height-adjustable driver's seat. SE has alloys and a leather-trimmed steering wheel, while top-of-the-range Sport models have a sports suspension and front foglights.
The Mii was awarded a five-star safety rating by Euro NCAP. Every model in the line-up has four airbags and anti-lock braking, and all but the entry-level S model also have stability control. The Mii also protects itself reasonably well against thieves; Thatcham awarded it for out of five stars for resisting drive away theft.
The Mii is good value compared to most other city cars: it's cheaper to buy than an equivalent Panda, for example, and should cost less to run. However, the near-identical Skoda Citigo is even cheaper, and its Volkswagen cousin, the Up, is classier.
