I had some interest expressed in the reflector piece between the tailights. JohnB tells me this is not a piece fitted to U.S. models? I removed it from the 540i to show how it fits - it's held in place with double sided tape only. As you can see from the pic there are 2 holes cut for the screws for the licence plate. I don't know if the position of the holes is where U.S. models have them.
The part no. is 8212 9 401 095
