Though it is permitted here, personally I don't think we need to talk about auctions; if you're bidding or want to and have a question ok- but just throwing stuff against the wall and calling the dealer a fraud ? Not cool.
The seller obviously doesn't know or care, the buyer should know better, and you have no dog in the fight.
You can't save everyone or maybe even anyone from being ignorant or catching auction fever. JMHO.
And maybe he had a reason- like having another '06 and this one would give him a consecutive numbered pair!
