I'm buying a car back down in Ft. Myers, but I live in Atlanta. I know that slapping the plate from my Trans Am on there is HIGHLY illegal and frowned upon. So how do I drive the car back from Florida into GA legall without having any issues?

I know this may be a stupid question but do they give temp tags at the dmv or am I SOL at the moment?

Edit: (Private seller, not at a dealership)
