<prompt> Human: Hi allIm getting ready to purchase a used 2013 Lexus gs350 with 60k miles for 21k. Taxes in my state are 6.25 and Im buying from a private seller. I will be paying the seller 3500 and financing the rest. Which financing term should I select? Should I do 60 months and take advantage of the low payments? But pay extra payments? Does this actually knock down your principle? Or are you paying towards the interest first? Should I do 48 months? Will I end under water on this loan if I choose either of these options? Interest rate is 2.9  <response>: You will end up underwater on nearly any car loan you take for the majority of the life of the loan because cars steadily depreciate in value.Are you already approved for a loan and considering options that have actually been presented to you, ie, how real is that 6 interest rate?
