Thinking about buying a used Expedition...please help.

[Guest]

I figure this is probaly a pretty good first post. I am selling my Vortech supercharged 1991 Mustang GT, and I am considering buying a used 97-00 4x4 Expedition. I have no clue what to look for when I am looking at used ones, so any help would be great. I am new so please go easy on me
