Is SC or GA more car hobby friendly?

So the Title Ad Valorem Tax is a one time tax, not a yearly tax? What's the "birthday tax"? I did see GA has an antique plate. Kinda lame actually.
Can any SC members comment on the vehicle property tax and how they determine the amount?
I only drive the cars a few hundred miles a year if that. It will suck to pay a lot to get only a little out of it.

I'm good for emissions tests in GA. The three possible counties we're looking in are exempt.
Thanks
