I saw this one in a parking lot a couple of weeks ago. It had what looked like all the correct insignias, and it had a white oval with a black "D" for Germany on the back. On the front, it looked like a different emblem had been there before. It looked familiar. It took me a while, but I finally looked it up today. It was an Isuzu Trooper.
I think that playing with badge engineered cars is a great idea. The Trooper had so many badges that it had no identity whatsoever. It brings to mind the US market Isuzu Rodeo / Honda Passport. A mix of emblems would be pretty funny.
One thing I haven't seen in the US is the current Euro country identifier on a car. I have looked for the little blue rectangles with the European Union stars and the country abbreviation that are on the left of their license plates, but I haven't seen any for sale. American license plate openings are often large enough for Euro plates, but we have smaller plates. It would be easy to just stick the Euro rectangle next to your plate and have the look.
