I'm not fond of documentaries (the original purpose of the site is referencing cars playing a role in movies, not just making a car picture database), but I guess that they may be interesting indeed; I asked other admins to give their opinion.

It would be interesting to have a short summary of each documentary (description/purpose).

About what to include from these if they are accepted, it should be limited to vehicles on which the documentary focuses, and not too many of the (back then) ordinary vehicles just passing there from traffic shots. Though that for old ones, it is less strict than for newer ones.
