I got the Daimler/Fiat allusion. But I don't think the "nationality" of a car is determined by the nationality of the parent corporation. Were Volvos American cars when Ford owned the company? And are they Chinese now? Nah! They're Swedish, have always been Swedish, and will remain Swedish unless their Chinese parent company chooses to close the Swedish plant(s) and move 100% of production elsewhere.

Conversely, "nationality" is also not determined by the actual place of manufacture. A KIA made in Lagrange, Georgia or a Hyundai made in Montgomery, Alabama is still a Korean car, not an American car. For the last couple of years the original Volkswagen Beetle was in production, they were all made in Mexico. Not a one was made in Germany, but they were still German cars, not Mexican.
