If it was a fake, it was a very good one. My wife has looked for the details and everything was identical like at the police-cars, she had seen in New York by herself.

There are some imported original US-police-cars over here. A few weeks ago I've seen annother one in Dortmund. But I don't remember, if it also had a Düsseldorf-plate or if it was a N.Y.P.D.-car or from annother US-town.
