I almost bought one when Chrysler had the 0% financing... and huge rebates. I am kind of glad I didn't because I would have been in debt and I love not having a car payment. I researched the crap out of those cars, most common problems, all the options... all the options year to year etc.
07 Have the slotted rotors that help with the annoying brake squeek problem that the 05-06 have. It also has some new colors and a 0-60 calculator built in. Many of the guys are in the 4 seconds going 0-60 stock. Pretty insane.
