My current rate for my car loan was 11.9 till I refinanced. Now its 9.19, but I still have a negative item on my credit report that will be on there till 2011

I tried to remove it, but they said they can't and it would be against the law if they did... Honestly, I just want to pay off this as quick as possible, however according to my scores and etc they save I do not have enough credit experience. So I am unsure what to do in that case...
