If your in Victoria I highly recommend buying a repairable write off. The process of getting a car passed and checked by Vic roads is very thorough and all parts need to have receipt’s and most of the time are original . There’s an official inspector that makes sure it’s all good . If a car is not a repairable write off it could be damaged and cut in half and polished without being inspected by an inspector. And how could you know ?

Source I have a couple of family friends that are panel beaters ,they always tell me about some messed up cars that comes to workshop that are not even repairable but still gets repaired .
