Financing help needed.

Jeffblue

i only got approved for 5.75% even though i had already financed a car through nissan that i had bought at the same dealer (great neck nissan). they tried telling me i didn't have enough credit history. i said 'HELLO i just paid off my altima last month after 1yr 11mo. Turns out i never got any credit for that because my dad cosigned on the loan. I got them down to 5% through fifth third bank. I didn't care that much about the rate though b/c i put down 30k and only intend to keep the loan a year
