And, for some more who owns what info:
VW owns AUDI, Lamborghini, Rolls-Royce and Bentley. Other makes include SEAT (family cars, Spain) and SKODA (family cars, the Czech Republic). It also holds a 34% stake in Swedish truck maker Scania. VW's other interests include consumer financing and Europcar International (car rental). The German state of Lower Saxony controls about 19% of VW.
And, of course, Dodge's parent company is probably more German than American (taken directly from Hoover's):
DaimlerChrysler, the world's #3 carmaker in sales (behind General Motors and Ford). Formed by the $37 billion acquisition of Chrysler by Germany's Daimler-Benz in 1998, the company makes about 4.7 million vehicles a year. Chrysler's brands include Dodge, Eagle, Jeep, and Plymouth vehicles; the Mercedes brand is limited to luxury sedans, commercial vehicles, and SUVs. Also, DaimlerChrysler's Freightliner unit is the US's #1 heavy truck maker. The carmaker, which has announced that it will cut 26,000 jobs over three years at its troubled US-based Chrysler division, has a 10% stake in Hyundai Motor and a 37% stake in Mitsubishi Motors.
But all this consolidation has some holdouts (good, I think). Honda says other carmakers can merge all they want, it's staying independent. Toyota's also independent, but I haven't heard any statements that it does or does not want to stay that way.
BMW sold Land Rover to Ford (but kept the Mini brand) and dumped Rover Cars for $15. Really. Anyway, the family that owns a lot of BMW doesn't seem too hot on having the company taken over.
