For a first car, you should think about something reliable and reasonably safe. You're in Michigan, so a 240SX is not a good idea. Lightweight RWD cars like that are certainly fun and interesting in the snow, but not something you want to be depending on in the northern climate. If you can find one, an 80's Audi is a great way to go - AWD, 5 cylinder engine, and it'll run forever if you change the oil regularly. A former cop car is not a bad choice, either, but make sure it's not been severely beaten on by anybody else.
I'd definately stay away from a RWD V6 like a Mustang or Camaro, because they're not only not that fast, but they draw way more attention than they deserve. I learned that one the hard way.
