Very true and applies to all 3 classes/types. Exactly the reason I have stayed away for the most part from restoration; too many rules, self proclaimed experts, haters, etc. For me, I grew up when these cars were new and got into them when they were in some cases 2-3 years old. I seldom saw a stock one, especially any performance model. Therefore I grew up modifying and fixing them. I can appreciate a stock/restored car but to me they are very boring. Don't get me wrong, I prefer a restored car over a badly built car, but I will go straight to the restomods, pro touring and G machines every time. I really enjoy seeing how people did things and how they made their vision come to life.
the thing I like about Pro Touring is that they take things to another level; complete suspension changes, very innovative interiors, etc. They are not constrained by what the car came with and could have came with. Personally I am in the middle of restomod and pro touring, I like innovation but I do like the period correct nuances as they take me back. Again, the titles don't mean anything, you can call your car whatever you like, sure their might be someone who disagrees but unless their name in on the title to the car it doesn't matter. If you are happy with the car, that is all that counts.
