You can do a customized appraisal on your '01 Santa Fe (look for the button as you drill down with the True Market Value tool). You should get a value somewhere between $12,800 and $15,900 or so. Note that neither Edmunds or Kelley will actually buy your car - that's up to the dealer or the private party you're trying to sell it to - so you have to take all these published prices with a bit of salt.
