I like BMW simply because they've been progressing to be better and better each race. I root for them to win a race, they are no doubt the 3rd best team of the 2007 season.
Since BMW Williams, they haven't been as strong when they had Ralf and Montoya then...
So they've been picking up the pieces and building a nice car and a nice team I'd say. But McLaren and Ferrari will always be faster. I hope Renault gets back into the mix in 2008, kind of stupid seeing them run so poorly this year.
