<prompt> Human: Just leased a new car, 36 month, 10,000 miles a year. I thought I did the math and even double checked the math but I mis calculated not taking into account a few days a month where I travel much further than usual. I actually need 12,000 miles. Should I contact the dealer and see if it can be adjusted or bite the bullet and pay the extra 0.25 per extra mile?  <response>: After triple checking your math, your title said you needed an extra 2,000 miles a year before stating you need 3,000 extra miles.It might be time for an independent source to handle the math before making any decisions.
