Hi,
i found 3 interesting documentaries at the SWR mediathek (http://swrmediathek.de/index.htm) with lot of interseting material for IMCDb.

"Als der Südwesten fahren lernte" (http://swrmediathek.de/player.htm?show=8d404830-9a57-11e4-abd3-0026b975f2e6). Mainly contains short films from the mid 50s to the 80s.

"Mythos Porsche 911" (http://swrmediathek.de/player.htm?show=87e4a750-9665-11e4-bfa0-0026b975f2e6).
Loads of Porsche 911

and

"Das Lexikon der Automarken im Südwesten" (http://swrmediathek.de/player.htm?show=9d87b4b0-8ffa-11e4-ad81-0026b975f2e6).
Covering both old and modern cars.

Would be nice to add them if you are ok with it.

I might be able to fill them with several pics (need to find some time though).
