Most of this information was printed in the June 1992 Roundel:
The Magazine of the BMWCar Club of America, Inc. It first
appeared in "BMW Down Under", the magazine of the
Victoria Chapter of BMW Clubs of Australia.
Thanks to the author, Bob Murphy.
Off hand, I don't know the designations for the current 7 series and Z3.
(Maybe it's Z3(?) for the later.)
