Hey guys,
in the fall of 2012, I hope to spend a semester at an American university in Georgia. Though I am familiar with the United States (I've been to a lot of places plenty of times), I am not a US citizen and not quite familiar with how buying a car works. What I do know, however, is that public transport in the US can be a bit of a pain in the, well you know, especially in comparison to Europe (which where I am from). Therefore I was thinking about having a car, but renting seems a bit too expensive. I am 21 and they'll only rent cars at regular rates to people who are above 25 and even still, it is pretty expensive. An alternative would be buying a car and then sell it again but I don't know if that is a realistic choice. Is it possible to go to a dealership and make a deal like that? What I know about American dealerships is that they have these cars stockpiled and that they are relatively cheap. Rationally, I would think it would be possible to own a car for three months and easily sell it, but I am not sure. What do you think? Realistic or bat-crap crazy

?
Thanks in advance!
