Which is right for you?
Pick Dealer Financing if…
Almost always your default. Get pre-approved from a credit union, then let the dealer try to beat it. If they can't, you keep the credit union loan.
Pick Credit Union Loan if…
Only when the manufacturer is running a genuine 0% / 1.9% subvented APR promo and you'd qualify — those rates are subsidized and unbeatable.
