My old man picked up black 15 platinum demo for $51k this past August. It had 6k miles on it. It Was completely loaded 701a, 4x4, bed liner, wheel liners, max tow, 3.5EB, moon roof, fx4, wheel liners, 35gal tank, and other things I am most likely forgetting.
CPO bumper 2 bumper last only so long. After that time you have a $100 deductible. i.e. options and milage?
Need more details, other than price.
