Monkie,
www.factoryfive.com. For about $5 they will send you a copy of their DVD. It contains over an hour of great footage about Factory Five cars.
I haven't seen the DVS III tape/DVD but it sounds like a great video and the money goes for a good cause.
www.cobracountry.com. Go to the "books/video" link. You'll find several videos there that are worth looking at.
