Like:
AFL - Weagles (West Coast Eagles)
NRL - Melbourne Storm (damn the financial idiots that thought they could rort the system)
A-League - Brisbane Roar (formerly Queensland, changed when GC and NQ came in)
V8 Supercars - Ford, especially Dick Johnson Racing (Or as they are called now, Jim Beam Racing)
NASCAR - Marcos Ambrose (Back in a Ford. Even better)
Indy - Will Power (Fellow Toowoomba boy, how could I not go for him?)
Dislike
AFL - a few, mainly Magpies, Swans and Power
NRL - Broncos and Bulldogs
A-League - No one really, I don't follow it that much
V8's - All of Holden except Garry Rogers Motorsport
NASCAR - Robby Gordon (obviously), Chevy (the Holden equivalent)
Indy - Paul Tracy, Danica Patrick
