    Dealership cancelled my purchase.

    Usually dealerships have a dedicated individual for internet/web based inquries. Admittantly, many people are "fishing" but it is she salesmans responsibility to ferret out the details of a deal or weather the person is a tire kicker. Most people now days don't want to walk into a dealership...

    87 octane vs 91 octane
