Thinking with your head pays off for the very few that do it.
OP, If your car is paid off...or not paid off...why heap more bills on your head for an Evo? Sure it's a great car, it's fast and you think all the girls are gonna love it but honestly, it's not worth the car payment that's gonna come with it. Just keep what you go, save up some dough and get it later or get something else when you can afford it.
If you got flow....then do it.
