I have had LOTS of friends die in car accidents, and I probably should be. When I was younger I took dumb risks and did stupid things. Almost killed myself driving a 4 cylinder chevy with a blown headgasket and ZERO power. Regardless, but especially if you get a speed, above all else...
BE CAREFUL!!!!!
Besides, I think you need beaters. They are hella fun, you can dent and scratch them for fun, no car payment, never have to worry about "what if someone steals it" and you can do your own wrenching without worrying about warranties. I drove beaters since I got my license and never paid more than a few hundred for a car until I got my Integra, and even then it was only $3,000.... of course I made it obnoxiously loud with a big wing and wheels.
More on topic: The financing was MUCH better on a brand new MS3 than a used MS6, plus for 2008+ the warranty was extended to 5 years or 60k miles. That is what put me into a MS3. Which one did I want more, the MS6. The sedan is sleeker and I love the look of dual exhaust look. The awd hooks better from a stop, but you can live without it. I will also agree that the 3 is more fun to drive... can't quite put my finger on why though.
