Love or hate him, he gets the viewers in and represents TopGear.
Personally, I love him but then again I love anyone who challenges the status-quo. One news commentator said " Of course people will dislike him, he was Nigel Farage before UKIP" this summed it up. He is original albeit sometimes inappropriate.
Love how David Cameron put a spanner in the works by showing support for Clarkson, clearly a stab at the BBC over the debates fiasco.
