Anyone in your family a GM employee or retiree? If so, you can get GMS pricing, and save a boatload, PLUS any cash incentives they have (which won't be much right about now, with the 2007's still on the lots)... Lease calculators aren't great -- problem is figuring the residual value AND your interest rate. Interest rate is dependent on your creditworthiness. Best bet is to take a deep breath and go and sit with the F&I guy and just run the numbers, without signing ANY paperwork. Perhaps you're also a member of a credit union or could join one and get a better deal on a loan to make an outright purchase. Just some suggestions...
