Three snags in a "vetting" panel/process would be, to be able to find individuals who do not have a vested interest in the show, in their own dealership, or the fear that going against the dealers/exhibtors, would affect their own future purchasing with with them.

IMO, I don't believe you will ever find such an unbiased, unafraid or non-vested interest individuals... Good Luck!

Come to think of it, there are two who come to mind, Don Boyle and Don Bible.
