Actually the fixed destination charge is more for the protection of the dealer network than to benefit the sale of certain models. It is (was) price protection so a close dealer couldn’t advertise a $150+ lower price than someone that may be just a few hours across a State line for example. It still goes on today; the local Ford truck plant still applies the same destination charge to the dealer that is ten minutes away as they do to one a hundred miles away. Price protection not certain model promotion.
