I'm 31, bought my WRX last year, and my fiance loves it.
I look at it like this:
I could have bought an Infinity G37, or BMW 335i, or MB C class something, or Audi A4, or whatever... and I'd probably have been happy.
However, I WANTED the WRX. Its funny... that whole adulthood + income thing allows you to do what you want without apologizing
I'll probably tune this thing out and sell it to some kid who needs some help getting tail LOL
