ebay is an anonymous auction. Yes bid fraud happens, and not just on vehicles, but bid fraud happens in in-person auctions too, sadly it's part of having an auction it seems.

If you lose out at an in-person auction, how do you know that the bidder was genuine? Most times you won't.

To bad you missed out on this one, you better move on and start looking for the next potential.

If you are contacted by the seller because the high bidder doesn't complete the auction, then you should certainly negotiate assertively based off your last and highest bid. I wouldn't be mentioning contracts, reserves, or T's & C's, unless you want to scare them off and lose your chance again.
