Buyer Beware - Rick Ehrenberg

I used to rebuild engines for a living (nothing exciting, my part consisted of all most assembly line style work)

There were probably a dozen of us who worked at this shop, and each of us had a unique paint marker (mine was yellow)
Certain key bolts would get a little dab of paint (head bolts for instance) and once that paint "seal" was broken, our warranty was gone

My point?
When the seller got "his mechanic" to start messing with it, he muddied up the waters far enough that I can see the seller backing off on it, simply because it now is impossible to tell who caused the problem
