I think old cars would make terrible EVs. The wind noise the rattles, etc. So much of that is covered up with the sweet sound of V8 music. EVs certainly have a place, but its not in the engine compartments of old muscle.
The best thing about old cars is the sound. Take that away and you've ruined it.
Friend of mine has a Tesla...thing runs 9s stock, 60 foots like a dud though. It's crazy, but it's like driving a stupid fast golf cart, according to him. He also owns a couple of FAST mustangs.
It's neat and all, but meh.
