I purchased a car a while back that I had been wanting for a while and in retarded excitement, I payed no attention to the paperwork and what not.... Now, the payments are fine but the interest is so high and that is all I am paying and have been paying!! Now, the car has depreciated a great deal and I am upside down by $7000!!!!!! ****** I believe it's called the Rule of 78's.
My question is; Is there any way to over come that without jumping futher into debt? Anyone savvy with finance or anything?

Please do not make this a, "Your dumb for not reading the contract" thread, I understand my mistake and do not need total strangers commenting on the obvious!

Thanks in advance!
