So, a '90 car is an antique now? I don't think so. I'm almost 65 and I think anything made when I was a kid is an antique. Anyway, these catagories probably won't mean anything until some kind of national governing board makes them official.
It's true that old cars don't have the metalurgy/technology of the new ones. Still they were overbuilt. They had heavier gauge metal in the body and extra iron in the block and such. The same with GTs. When did the builders start saving money by making them flimsier? Using alternative materials such as alloys and plastics.
Let me ask another question: what is the Golden Age of GT styling? I would say the late 60s. For cars it was the mid to late 30s.
