I want to apologize right here and now to Drew for my earlier comments instead of just sliding him a PM..
Drew, I'm sorry for my harsh words previously!.
Seeing you haven't left the table and are sticking w/ this situation and thread also considering possible solutions, it's looking more like you are in fact THE auction house that actually does give a sh!+ afterall!.
Lots of great ideas especially posting the Vins previous to the sale!.
Obviously it'd be tough to act on lone comments but if real evidence is presented or someone w/ known credibility claims a car is a rebody, what do you do then...pull the car from the sale or continue on but as an admitted rebody?.
Sure not all here will agree and you'd be losing commisions on questionable cars, but refusing outright rebody cars from your sales would certainly be a conspicuous difference to other auction houses that didn't do the same?.
And no arguing it's sometimes a blurry line between a rebody and a correctly repaired car that was perhaps rough to start with, but there is a difference in spending fortunes in time and money correctly repairing an original car to that of transfering an identity of some significance to a different vehicle...whether someone's done a good or bad job of hiding their tracks or not..
