The difference is quite simple, Americans and Britons think it is "all about money". At least they did in the auto industry. In Germany, there is more than money involved in the car business. Boys become engineers because there is a long tradition of craftsmanship, because their fathers show them all sorts of ancient and current locomotives, aircraft and so on.
VW's long-term CEO Ferdinand Piech has an aeronautical engineering degree, which is much harder than mechanical engineering. So he has the best education you can get on earth for making cars (and many other machines). Compare that to the GM CEOs, who are all Master-Beancounters. Their cars are consequentially crap and rational buyers go for German or Japanese cars, even if their purchase cost is higher. TCO will certainly be better, as VW cars normally just don't break (except for regular wear and tear).
