Hi, the only thing I can think of is looking to make sure the head gasket hasn't gone yet, or asked them if it's been replaced, because on the 2.2L's they seem to go. But mine didn't go until 160 000kms. As for everything else, I'd just be looking for wear and tear, make sure you don't see any paint that looks like it's been touched up (meaning that car has been hit before) or other little things, I'm sure someone else can help you a lot better, those are just some things I can think of.
save your money and get one with a 2.4 engine. more power for ya
