Never had a vapor lock issue even on 100 degree high humidity days -- I wouldn't worry about it. Since the best part of the driving season is pretty much over, I think you ought to wait until the spring and use the time between then and now to learn the zillion different things there are to learn about these cars. Somehow I read your first post to mean you were just going to have ERA build you a Cobra to your specs. Buying a used Cobra makes it a little trickier, but frankly it's probably a better idea money-wise.
