I still think Alonso was the star of the season. Vettel always had the superior car, except for reliability issues mid season. So I was not surprised he came from last to almost win in Abu Dhabi. He's a good driver, but put him in Alonso's Ferrari this year and I don't think he would have finished 3 points behind Fernando.
And let's not forget, this would have been a different championship if Alonso's lead had not been erased thanks to ham fisted drivers like Grosjean at Spa. This was a tremendous season and I'm already waiting for 2013 to begin.
