Presumably its being MOTd by the importer?
Things I would check:
Obvious damage and poor repairs (masking lines near windows are an indicator)
Wipers
All lights / mirrors (is power)
Air con
Seat belts
All other interior functions
All fluid levels, filters and condition
Check engine bay for leaks and visual damage
Check aux belt
Remove plastic plug cover - check condition of plugs and cam belt
Crank pulley damper rubber
Engine and transmission mounts (facelift mounts fail)
Get it up on a ramp, inspect brakes, wheels/tyres, suspension, wheel bearings etc. Tyre wear should indicate any serious alignment and tracking issues. Check all lines, transmission and lower engine area for leaks and damage.
Check battery and starter function on startup, and look for any exhaust smoke. Make sure the car engages gear and pulls away smoothly. Listen for any unusual sounds, steering pulling, vibrations through the wheel or car etc. Check gauges, ensure car is boosting correctly if its a turbo.
Consider taking a friendly mechanic if you're not 100% on the things you should be looking for.
