are the 300ZX's prone to rusting or "body cancer" as the guy on the phone called it. I got off with a dealership and the car I was talking about was an '85 300ZX 2+2 and according to him, due to the type of metal used in these cars, there was serious rusting problems and eventually all had this issue. never heard this before and I think its complete BS. All cars rust but I don't think 300ZX's are prone to it. Anyway, I just wanted to check and see what yall thought. Can anyone who perhaps knows make a statement on this?
