You're still pretty young I think, and since aren't asking for advice... I'm going to give it to you anyway. :-)
Take it from someone a little older, cars and fast living won't make you nearly as happy as building up your capital so that you never have to take shit from a boss or a client again. I chased that fast life in LA for years and thought all the toys made the bullshit worth it, but man, when you have freedom, real freedom, to do what you want, when you want... you'll wonder why you ever parted with a penny that didn't have a return attached to it.
If fast cars are your thing, buy one after you build enough capital to never have to work again.
