I'm a friend of FastCars, and was watching the auction end live, refreshing the page frequently in that final countdown. Got a text from FastCars that he'd won after he saw the auction close info. I refreshed one last time not too long after the auction "ended", and no longer saw bidding/auction information on the page at all, just whois info. I thought that was a sign that everything was finalized (never used the site before, so if I'm wrong on that, it's inexperience)... until I got a follow-up text a few minutes later from FastCars that said the auction apparently re-opened.
What's amusing to me is that if 420domains intends to resell the domain at a profit... they just outbid probably the only person on the planet who would pay more than a few thousand for that particular name (as some here have noted... it's not an otherwise "valuable" name, it just has unique value to FastCars). I think 420domains just wasted tens of thousands of dollars.
