The Mii is a rebadged VW Up!/Škoda Citigo sibling with a small naturally aspirated 1.0 petrol and a 5-speed manual; it’s mechanically simple with no DPF or complex hybrid systems. Parts are common across the VW group so repairs are usually straightforward and affordable, but interior and boot space are limited compared with larger hatchbacks.

• Clutch bite point and gearshifts for slipping or crunching — manual clutches on city cars can be worn from stop/start driving.
• Starter battery condition and charging behaviour (slow crank after standing suggests frequent short-trip use and a tired battery).
• Front suspension and steering for knocks or excessive play from pothole damage — listen for clunks on uneven surfaces.
• Lower sills and wheelarch seams for corrosion, especially around rear arches and door bottoms on a 7‑year‑old Irish car.
• Boot floor and rear-seat folding mechanism for dents, wear or stiff latches — small boots can show heavy use if previous owners loaded them often.
