My, what fun we used to have shouting "Vorsprung dürch technik, mate!" whenever we drove past a hapless Audi driver waiting for the RAC at the side of his broken down car. Happy Days.
BTW: I think you're right, ReiToei - the phrase was the invention of some faceless ad-man. One reason that the phrase wasn't particularly liked by Brits is that it's somewhat reminiscent of "Arbeit Macht Frei".
