I traded up after 7 mths with my LT. Did I need the power? No. But I wanted it. Plus my payments only went up an extra $40 bucks a mth for a brand new '11 SS/RS. Its very unlikely you will walk away wo being upside down in your current loan, the important question is how much.
Ohhhh and IT'S WORTH EVERY PENNY FOR THE V8!!
