Since I was a Senna fan, my thing has always been McLaren, but for the first time in decades, they won't have a lineup that I actually like and now with Mercedes buying the team, it's likely I'll drop the support.
I never had much gripe with Ferrari, but more with Schumacher. So now that he is leaving and Kimi is getting in, I'll probably support them, and Kimi who is my favorite driver at the moment. So wherever he goes I'll be fine. Other drivers that I like are Pedro de la Rosa, Jarno Trulli, Heikki Kovalainen and now Robert Kubica as well. I guess since I'm brazillian, I'm forced to kinda like Massa and Barrichelo too, but since Senna, there hasn't been a brazillian that I've been particularly impressed with.
As for teams, I like some of the midfielders, like RedBull and BMW too. I don't have any problems with Williams either. The back teams really lost it for me after they were bought though...maybe not Toro Rosso, but Midland was kinda crappy...maybe they'll get better now with Spyker in the game...
