since you probably won't get much of a chance to drive the car, I would just invest the money. Go to a credit union near you and see what kind of high-yield accounts are available (money market accounts are in the toilet right now, but when I talked to my banker recently, she showed me some accounts (special type of CD iirc) that had 4+% interest rates and you could choose a 6,12, or 18 month term to leave your money in there (obviously, a longer term means a higher interest rate). Put all of the extra money you earn into accounts like this, and when you get out you can go buy a nice sport-lux without financing it. Buying a car (other than a collector) is one of the worst financial investments out there. And since you probably won't have a chance to drive the car, there's no "happiness" return either. No sense in buying a car now to let it sit for several years. When you get out, you'll have more money to buy the car you want, and the cars you're looking at now will be cheaper.
