Its had its fair share of welding but i have seen worse ones. I think that it i less work to repair as much of the origional panels (in his case ALL the panells) rather than replacing them as if its not completely broken why dismantle it further?
Its got 5 years of dirt on it but it starts and drives nice from what ive seen and i am brining it back to a state that is never going to be a perfect off the factory quality but it will be presentable and it is what it is. I have some pictures which i will upload depending on wether or not i can do it from my phone

lemme know what you think
