Nah Ben, the way it panned out looks completely legit if that's what you were unsure about. I've done the same thing where I've placed a maximum bid then wondered if I've bid enough (even while I'm still the highest bidder). I've then increased my own highest bid. I missed out on a pro street Sunbeam Tiger on Ebay when I was down at OZVENOM's place a year or so ago by not increasing my highest bid when I knew I needed to, but I'm not bitter...!

The winner of the Cobra could have put a highest bid many thousands above what he actually paid, but without bidding against anyone we'll never know how high he would have gone.
