Not exactly specific to resell, but my state has antique plates available for vehicles 25 years and older - pay a one-time registration/plate fee of $20 for as long as you own it. So in my case, yes if was advantageous to title as a 1965 - and they allowed me to put an antique plate on it. (No difference in practical value however.) Other states will have different policies and practices. I think you just have to study which state is more favorable to you from a registration and tax cost standpoint (if you have a choice).
The also titled it as a 1965 Ford Cobra. They were supposed to put the word "replica" on the title, but they forgot. I doubt that will convince anyone to pay me anything more for it however.
