Buying a used Rolex! Help

[sethfhy]

Hi everyone! I am looking to buy a used Rolex DJ and have found one I am interested in. I will post the sellers pictures and description and would like to know some of your thoughts. Also what would you say is a fair price for this watch?

Sellers description: "-Two tone men's Rolex Thunderbird Datejust Turnograph is in great condition. It runs perfectly and keeps great time.
-It is complete with all original boxes, paperwork, hangtag and even the original receipt from 2003.
-It has scuffing throughout from normal everyday wear, most of which could be buffed if new owner chooses."
