Mate, theres no way in hell.
He's already in the best V8Supercar team, with one of the best co-drivers and the best crew. He leads the championship with SBR and he's not the type that would switch for the money - and Ford is paying him a far bit as it is.
Having said that I'm sure he signed a contract earlier this year with SBR for the next couple of years, and I think he has a 5 year contract with Ford.
And he looks fairly happy where he is if you ask me!
