Not really TV commercials, but Videos are contained in at least two DaimlerChrysler sources:
CD-ROM "Die grosse Automobilgeschichte von Mercedes-Benz", United Soft Media, available from DaimlerChrysler; in German language. It contains a vintage Video of the 230SL with driving demonstration by race driver Karl Kling on the Untertuerkheim test track, approx. 3 min (and, of course, a lot of other info about Mercedes and all models since 1886);
DVD "Faszination", 2 DVD set, in German (may also be available in English), with Video of the Pagoda from the 230SL via the 250SL to the 280SL, with some driving footage same as in the other CD, also only a few minutes long.
