You're willing to lose a couple years of payments just to get into basically the exact same car? Getting a new car never makes good financial sense. But if there was a compelling reason for the jump, like getting rid of a lemon, or reducting a car payment, or getting into a Boss or Shelby, then I could maybe understand the appeal.
You have to decide if it's worth the ~$10-20k hit you're going to take after you factor in the depreciation of the '12, sales tax on the difference, loan interest, and depreciation of the 2014 over the loan.
Hey, I'm a dummy too, I also bought a new car a couple of years ago!
