Hello I just was approved for a loan on a 2005 Ford F-250 Harley Davidson Edition truck. I was approved through Carmax. My Equifax is 652 and I was approved for 32,000 (2,000 negative equity added to this number) at a rate of 12.25 for 66 months. Does anyone think I could get a better rate and if so where would I try? I would love 72 months and interest in the 8-9% range. Thanks Oh the truck is worth around 40K but because its has over 60K miles on it Carmax offers a special price. The truck is diesel with all the bells and whistles...
