How do you figure you'll save between $150 and $200 a month on gas and insurance? How much driving do you do monthly? And how could you insure a new vehicle for less than an older one? Then you have the added cost of new registration and plate fees too.

I don't have much experience with loans, but why couldn't you take out a home equity loan at a much lower rate and use that $ to pay off the jeep wrangler at the much higher rate?

I don't think taking on $18K of new debt is a good idea.
