If it sold it would show, ended by the seller could mean a couple of things, bids were bogus, he ended it early but he had no mention of the right/option to ended it early ie someone did a deal outside of the auction.
I hear about circumventing eBay auction with Daytona 500 tickets, many brag, I really don't get it or how they do it.
On the flip side of the I hate eBay coin, while reading up on BaT horror stories one guy in a well known long standing forum won a classic motorcycle that he really wanted, then someone contacted the seller outside eBay and bought it for more than the auction end. The guy wasn't short on means and got a lawyer and sued. Won the case, got the bike plus damages & court costs. shady shit I'll tell ya.
