<prompt> Human: Hello! Im 26 years old, bought my first new car in April of 2009. Did pretty well - the car was a 26K list price, talked them down to 21K with having no experience in buying. Im sure I could have done better though. Have had no issues with payment except for my second bill being a day late due to automatic bill pay breaking, and am able to get by just fine. Unfortunately, my dad his hit hard economic times and Im going to have to start pitching in to help him out - so I need to tighten my belt as much as possible. First thing I thought of was reducing my car loan payments.The numbers:6 Yr23,105.889.5 rate425 a month paymentExpected to pay out around 30K by the end of the 5 years.Down to 17, 091.84 with my next payment being my two year anniversary. I had a 720 small credit rating when I bought the car, and no big credit history.Currently financed through a large commercial bank. Was planning on going to a local credit union to see if I could A. get a lower interest rate, B. reduce my monthly payment. My question is - is it worth while? What kind of rate should I expect? How much could I reduce my payment by? Is this going to hurt my credit?I really dont have issue with extending the loan another few years if it means refinancing at a reduced price. In addition, my dad had said previously that you pay off your interest in the first two years of the loan up front, with any overages going to the loan itself, before you start making full payments on the loan itself. Is that true? Would I start seeing the loan total dropping like a stone in a few months?Thanks!  <response>: holy god, 9.5?I got 3 on my last loan. Assuming your credit isnt shot...it is totally worth it...youll save a bundle.
