<prompt> Human: About to buy a used car around 15k. The dealers price to finance with them is 500-1000 dollars less. Am I risking anything by financing for the lower price and then paying off everything with the first payment?Im in NY so the Rule of 78s type of loan is illegal, but Im not sure about other ways I may get screwed and end up owing more than if I just paid in cash.Other information if it applies: My credit score is fantastic, over 800 when we bought our house. Paying with cash wont break into my safety net so it wouldnt make sense to finance and go through with payments.Thanks!  <response>: Youll pay one month of interest, which wont be that much. The loan will cause a hard credit inquiry, dropping your score by 10 points temporarily. Make sure your loan doesnt have a prepayment penalty.
