Ditto, don't do it. Think of it this way: Pay off your present car and their will be a 2012 with 5000 miles on it in 2yrs and you will be that much ahead.
It is like buying "too much house", so much so that you can't afford to go out and have dinner and a movie or whatever so you are stuck in the house....you start hating the house real quick, and it doesn't help the relationship either.
P.S., the pic you have of the Camaro is a 2SS, as the SS badge is red. A 1SS will be silver...
