Will paying off my car early hinder my ability to build credit?
12% is ridiculously high and routine for loans with no credit history, esp. from the dealer. I don't think though paying off would hurt your credit - you've already got installment loan on your report, and you have history of payments, so it shouldn't matter how long the history is (warning: this is kind of guesswork compiled from personal experience and stuff read on the net, since officially how credit score calculated is Top Secret).  If you have the loan and credit card with good payments, only thing you need to build credit is time (and, of course, keeping everything nicely paid). Of course, if you could find a loan with lower rate somewhere it's be great to refinance but with low credit you would probably not get the best rates from anywhere, unfortunately.
