I found this site thru another forum. It's mostly amateur in-car videos, but there are some interesting ones. There are some skylines and 350z vids and drifting too. You have to signup to download. These are not dial-up friendly. The link is to the video of a world class driver in a bmw m3 gtr v8 doing a hot lap at nurburgring. This guy is definitely a step above the other amateurs.
