Go to this site, also lots of quattro rally action videos under Audi

Just explore the drop down menus. The Schwimmer is under "Spezial" under "Amphibienfahrzeuge"

There is some great stuff here. Audi tests; vintage Audis; Hockenheim Tuner GP; German Drift Challenge footage including the winning VW Superbug doing some nice smoky donuts; Worthersee GTi treffen in Austria; old Posche videos; roadtests etc etc

Just thought I'd bump this up a bit.
