ok, didn't read your first post...

Check your radiator. see if the coolant is there and not plain water. also dip your finger in it (of course when the engine is cool lah) to check for rust. rusty radiator no gd.
check the engine oil. check the area around the engine for oil leaks.dirty oil means never service for long time.
turn your steering full lock on both sides, and let go to bitting point. if got sound means axle bearing finish liao.
check for smoke.
check all functional buttons, power windows
if auto gear, check if gear changing sounds and feels smooth. check your ATF n see if need changing.
make sure your check ur spare tyre condition and tools present.
Check tyre threading. usually the dealers will kiwi polish the tyres but if you physically feel the tyre that comes into contact wif ground, mostly all koh yak.
