the following site is giving great odds for this years WRC, overall winning odds for team, driver, plus individual events.

I got lucky (i hope) and got peugeot as the overall winning team :)

Try Ladbrokes as well ( no Manufuacturer book open yet though )

I made quite a bit backing Burnsie throughout the year has the odds lengthened after each failure. :D
