I recently bought a new 2016 Altima SR w/ appearance package and traded in my upside down 2012 Altima SR. Score was 650s when I went to dealership for the car, NMAC was the only one who would approve me with no money down but at 11.89% for 72 mos at $609/mo (Crazy to have accepted it but I did). Felt I was taken for a fool as my scores should have qualified me for better rates so I went looking for refinancing that same week.
Few days later, coworker recommended her CFE credit union in Central Florida, and was able to refinance my brand new car at 6.75% for 84 mos ($482/mo) or 2.49% at 51 mos ($645/mo). Chose the 84 mos option as I didn't want over a $600/mo payment. I plan to pay down as much as I can for 1 year and see about requesting a lower rate/refinancing it again.
Definitely check out other credit unions even if you're not a member. I wasn't a member of CFE CU when I applied and got approved.
