dealerships don't prefer cash sales. Less money on the backend to be made i.e. they make money off your interest rate. Plus the chances of closing on warranty products/maintenance/road hazard etc. all goes down with cash buyers. Just bc you sign a paper saying you got 5.9% interest the bank may have said 4.7% to the dealer every point the dealer up sells they get paid on from the bank. Unless its one of those nationally advertised low rates on brand new car. Typically a cash deal goes so quickly and will get a dropped price bc they realize you have money and will do the sale as quick as possible just to move a unit and hopes of making money off of you in the future in the service department if they make you a customer.
