I have two GoPro HD Motorsport Cameras for sale, brand new & still in their original (unopened) packaging. Normally in the UK they are £300 new; I'm looking for £250 each.
They are awesome pieces of kit and perfect for filming from the car - they use a big suction cup and we've had ours attached to the windscreen and the rear wheel arch @ high speed on bumpy roads with no problems.
Video quality is excellent - you can film in 1080p, 960p, and 720p HD at 30 frames per second (60 fps in 720p). The sound quality is also excellent and picks up side pipes very nicely
You can also do time-lapse photography during your drive rather than video.
This is the camera pack:

These are some test runs we did with the Aero:
