I just tried to refinance my auto loan through HSBC and they couldn't beat what I already have. The value of my car is around $10k according to the rep. and I still owe nearly $13k. My mileage is excellent. He also said that because of my income they couldn't lower the rate or the payment. The best payment he came up with was $382/month. That's $70 more. I didn't even want to know the rate he was getting. I think 11.45% is extremely high, but he said it was good compared to what he came up with.
I'll try again in a few months when I've significantly paid the car down.
