Man, growing up in Germany, these thoughts of buying an M3 at 22 basically never enters your mind... I got a hand-me down beater from my mom at 18 and drove crappy cars until I got my first real job. And I though I (and my friends) went crazy when I bought a brand new Golf GTI.
OP: You make good money at your age, which means there is a high chance you'll make a lot more in a couple years. The M3 is probably not that far away.
