And here I though I was the "old man". What a bunch of responsible nerds you guys are! Did I see someone quote Suze Orman?! My Grandmother watches that crap. Shit, If I waited until I could afford a car by your guys standards, I'd be rolling to work on a Huffy.
It's not like the OP works part time at Taco Bell. If you can afford the payments, and want a car, buy a damn car before some wife puts you in a Prius or minivan. Be responsible (the kind of responsible these guys are talking) and save for you future children's education when you have some. Not saying anyone should go broke to buy a shiny new ride to impress people or something, but you certainly sound responsible enough to me to handle a car payment. I'd say go for it.
