After figuring out my budget, including all monthly expenses, I have $425 left over for basically whatever (my current aging car is paid off). I am wondering how much of a monthly payment I should make out of that on a car. I haven't really decided what I want, but I'm trying to figure out my budget before I take my info to the bank so I can get some quotes. Say you have $425 extra per month, how much would you spend on a car per month? I was looking at staying under $225 so I'd have a cushin of $200 each month.
