[voice of reason] You don't want to be struggling with the payments for years. Compare what the dealer will give you on a trade in vs. what you owe on the SER. You definately don't want to be rolling negative equity into the next loan. After one year of payments on my car, I definately owed more than it was worth. If money's an issue, you don't want to trade up to something that is depreciating faster. Think about how your priorities might change over the length of the loan.
