John,
never tried it before, so I uploaded a video from the GTD40 Club Gooodwood trackday 2004. There is an original version on the GTD40 website in higher resolution, this later version is edited with a grainy monochrome intro and ending just for fun.
YouTube - GT40s at Goodwood 1966 well 2004 actually
Ive got another one or two videos to upload too, maybe tomorrow.
Dave
