Grif,
Believe us, we ALL understand the desiring that one VX which is at your fingertips. We know that magical pull toward that first VX you see. But many of us have been here for years seeing VX's bought and sold, with those who take gentle, precise care of their rigs and others who absolutely trash them.
A truck that has so many problems that were not addressed by the past owner(s) will hide a multitude of hidden problems - some potentially dire to the longevity of the rig. I have personal knowledge of a Ebony that when it was sold, had a number of known problems never addressed, and when the next guy bought it, he had to put in over 8K in it, and it still wasnt right. It literally was too far gone.
We can help you find another VX - better ones ARE out there. Just be patient and look around. Many of us across the country check out rigs for others and we certainly can do it for you.
