Check gears 1st to 2nd and onwards and see how smooth the change is, check clutch for smoothness pulling away and gear changing incl reverse.
Test drive and check brakes incl an emergency stop.
Check tyres this will also indicate wheel alignment faults if wear is pronounced on a particular side of tyre.
Check for any leaks i.e. oil, fluids, water.
From what I have read the biggest moans seem to relate to gear changing 1st to 2nd and body paint where some feel that the finish is too soft and as a result may be pitted i.e. bonnet.
Check spare tyre and tools incl jack
