Markings of paragraph madness!

Hello, I am bursting with rage. I have today changed a stretch limousine from Munich to a neighbouring district with 3 letters. Up to the registration plate no problem either. Because the registration office was able to present me new regulations, which state that there is NO issue of motorcycle registration marks for cars anymore! Except only oldtimers and vehicles, which are already registered in the district. Alternative? A full size number plate with self-illuminating sign at the back. t: 150EUR. Apart from the fact that this looks totally shitty, when my license plate holder is empty, and for this the bumper with a license plate is posteriert, I get a decent attachment (adaptation to the bumper) cost of a total of almost 600EUR! I believe myself place immediately what! I should now attach this stupid full size license plate to the round bumper of a TownCar and put power supply from the lid down. That can’t be! Of course, the 355mm license plates were worn. The very short license plates were not available after the vehicle was measured and the license plate holder is probably 2cm too narrow. Does anyone have an idea how to proceed? The vehicle has to drive orders on weekends, and I certainly can’t find a workshop today that will build this self-lit shit properly on me…
