Bit of a field spread though, 2003 was interesting because of the tyre war. Renault only won one grand prix, McLaren only 2 wouldn't say that was consistently.
2009 however has got to be a strange season, would have liked it if Toyota took a win in Bahrain, I don't know why, just wanted them to win a Grand Prix. Also, I think 2009 was one of the closest fields ever! Only 1s covered the whole grid in most qualifying sessions.
