I would be tempted to say Vettel's final pole position lap. Hamilton had put the spot under pressure but his lap nicked it by 0.03 seconds in the end. It (just) got him into first corner leading, and let him drive on to take the title (and 10/19 poles for the season).
There were no real stand out moments in the race to celebrate.
One of the few highlights was Schumacher smiling while walking back down the pits after nearly having his head removed by Liuzzi's wheel. He really lets nothing phase him, I wouldn't be walking after an impact like that, my nerves would be shattered.
It would have to be Heidfeld setting fastest laps for quite a while in that Sauber for me, he was flying at the time and could have finished higher up if he had shown that pace earlier in the race or during qualifying.
