Dealer vs. Bank Auto Financing
A promotional dealer rate can be valuable, but it may replace a cash rebate. A bank or credit-union approval can strengthen negotiation and reveal whether the dealer offer is truly competitive.
Compare your own offersWhat decides it
Compare total out-the-door cost and loan cost together. A lower APR is not automatically better if it requires surrendering a larger rebate or accepting added products.

Should I compare monthly payments?
Only after price, term, APR, fees, down payment, and financed add-ons are aligned. Monthly payment alone can hide a longer term or higher total cost.
Can the dealer beat a preapproval?
Sometimes. Keep the preapproval terms available and compare the final written offers line by line.
