<prompt> Human: I just got a newer car because my old one was in its death throes. I have really good credit with sustainable income. If I were to refinance my loan in about a year and a half, what would the effects be? Would it be more advantageous to just pay off the loan over the course of 6 years or to get rid of the loan in 3 years or sooner? I really dont like having a large amount of debt over my head but I dont want to mess my credit score up by refinancing if thats what will happen.If I did refinance, Id be able to put down 5k towards the loan as a whole.  <response>: I refinanced my car after the first year and it ended up knocking my interest rate in half and taking an additional year off my loan. So I feel it was well worth it.
