Button wins the race. Vettel wins the Championship. This was a messy race in some ways ~ certainly for Hamilton ~ to end his season and drive with Mclaren ~ and a disappointment for Alonso and Ferrari - though still a very competitive season and finished second and third in the race while also finishing second in both Drivers and Constructors Championships. I think the rule changes this year had several former World Champions vying for the podium. A dramatic season with brilliant drives from many.
Congratulations to 2012 F1 World Champion Sebastian Vettel - and Red Bull Racing - youngest ever three time champion and all in a row no less!
