Not to step on toes here but what about this link that was posted a few days ago about this car? It is the very same car on ebay and seems to have been built up.
The asking price on the website was only $18,555/offer plus the dealer is in Wisconsin. Looks like it was sold there as well.
If I was a bidder on ebay with a $30K plus bid on this car and found this link I would be very, very unhappy.
You make the call.
