I would pick the 0% or .9% if you have the credit. All principal. Take the dealer discount and the special APR. Screw the rebate. Dealer discounts can be pretty good if they are a higher volume dealer.
truecar.com will tell you what dealerships in your area have been doing for deals based on registrations....which is the same info dealers have been using for years! even offers a best price guarantee from a participating dealership. why give yourself a headache haggling from a position of weakness?
