if possible id try and get a check done on it before you buy it just so you know what your in for.
as stated above State Roads do a very thorough check on a car compared to say an racv check.
i do roadworthy checks at my work and we check things from...rotor thickness, pads, tyres, shocks, screen, seatbelts, dash controls, check for jig marks and evidence of accident...even if the oil is low just to name a few.
as said if the guy says its to much hassle to get a roady done on it then id be careful.
