ah k thx for the replies guys
i had a pretty good long look at the car, all pannels alligned etc, paint was probs better then expected so im thinking maybe it was in an accident, but just wanted to clarify with the bonnet poping as that stuck me as being really wierd, but ima check it out again and ill look closer this time to the chassy and if im still keen ill get a inspection from a racv or state roads who will go over car properly mecanhically and cosmetic damage so look for weld marks under car / behind bars etc to help me make a better decision.
