In my opinion, I think the seller is making a mistake by putting a car of this caliber up on ebay. It's clearly an exceptional example, but he now runs the risk of it becoming "that car from ebay that didn't meet reserve." It will feel passed over. Part of its mystique will be gone for the foreseeable future.
(If you absolutely HAVE to sell a car of this caliber on ebay, then at least lay out an attractive page in HTML with oversized pix throughout, not the standard ebay auction layout.)
