Thanks,
Dackelone !! I agree 100% if you dont own these or you haven't seen them ... do it!
Since we're on the subject, I want to recommend another to you that came out just this past November:
Journey to Le Mans
It is by Charlotte Fantelli and narrated by Patrick Stewart

It's not BMW-centric but it is excellent
