In the late 1980s, BMW wanted to push the envelope of what a flagship could be. It decided to build a sedan larger than the 7 Series. You've probably heard of the "Goldfish" aka "Super Seven" from 1988 with a V-16 engine, but a second car was assembled two years later. It's been kept secret for decades, until this month when it showed up at the Techno-Classica Essen.
