When the M coupe was released and shown at auto shows in the US, it frequently had a special license plate on it. I got one circa 1999 from my dealer parts guy. I have it hanging in my garage. Years later, I was able to locate an M3 one to match. There is an M roadster version of this plate, too. The gray S54 M coupe is a picture I took at the LA Auto Show when the S54 M coupe was first released. It has the same plate. The picture is time stamped 1/5/2001.
