I don't know of any legal way to see coverage of the 2007 World Rally Championship in the US, especially since Speed Channel replaced their coverage with "Pinks," or left-turn racing or kids racing in go-karts or whatever BS they replaced it with. Anyway, I recently got word of these three sites which have the full rally coverage available for download. Note that's 1GB of video per rally, broken into 250MB files.... just something to do while you... sleep. Also, keep in mind running those websites takes quite a bit of storage and bandwidth if a lot of people start downloading.

Also, in other news, if you wanted to know how fast these rally cars could be if they weren't restricted... enter the Citroen C4 Rally Cross: 2.0L four-cylinder turbo: 518hp, 4WD, sequential gearbox... 0-60 in 2.39 seconds. The europeans have a very different definition of "rallycross," than Americans.
