Welcome to the RTA Forum!

I can't begin to tell you where you could go, and its a question that's probably too far away from the focus of this site to get the answer you are looking for.

In any case, I will remind you that it is quite possible that you would not be able to bring a car from South America to the US. It's unlikely that such a car would meet US emmission standards, not to mention, you'd likely be looking at pretty severe duties and taxes for attempting to import such a vehicle.

And of course, you've got the Darien Gap that would prevent you from driving into North America.
