Buy an NA Supra with an LSD, don't spend a cent on it, enjoy it for what it is and sell it once you're off your P's.
People will go on about how you should just save all your $$ till your off your Ps, but if you need a car when you're on your Ps may as well get something decent, thats done the worst of its depreciating already and is reliable.
The key is to NOT modify your NA car, and just enjoy it as a nice A to B daily.
