Thanks to all of you that replied via PM. There really are some great people on here. I have gained some insight on your experiences with the 7.3.
And... Fair enough... the point here was not to undermine anyone's sell price, or to start a combative thread, I was simply trying to get a baseline, not having owned one before, I am looking for input.
Jage, I really have to disagree with the "whats it worth to you" philosophy. That is what got the financial sector (and the rest of the world) in trouble. There is a fair market value for everything. Assuming most of us on here aren't sh!tt!ng money first thing after our morning coffee, and the fact that this kind of money would fund a solid room addition to our homes, leaves PLENTY room for discussion of fair market value.
That said, the $70k is obviously fair market value for the seller, and it is equally apparent he is not that hot and heavy to sell since an 02 7.3 with 71k miles with gutted and rebuilt 2012 interior just sold through sportsmobile for $60k.
If I were him though, I wouldn't want to sell either. That is the rig I am looking for, unfortunately, the price is prohibitive... not because I am cheap, but because I simply don't have the means to make up the difference.
Good luck Daryl, it is a really nice rig, and obviously well cared for.
