Realizing now that maybe I should have waited a bit to sell my '75 TS250. Holy crap.

There's something fishy going on with that one!

Notice the winning bidder "Ggracing" beat out one of the other final 3 bidders "gracing", and gracing only has made 7 bids all of which are on this bike. The other bidder "99oneTcab" seems legit and has won several auctions.
What are the odds that there are 2 bidders going against each other on the same auction in the last few hours named Ggracing and gracing?
