Bigger is always better right. I think 8k is a good start but the more you have the better off you'll be. If the STi comes in at $32k you still need to add tax, title and license (not sure how much but lets tack on 3 grand). You have to finance 27k. For 60 mo's @ 5.5% your car payment will be $515.73 not including your insurance. If it's 35k before tax, title and license. It only gets worse.
