The L’Universelle was a big hit at the Motorama, so much so that it almost went into production.
GMC went so far as to buy a metal stamping press that could create its roof in one pressing.
Then the bean counters did the sums and it was discovered that a production version would cost more than a Cadillac to build, because the complicated front drive V8 layout would be unique and could not be amortised across other cars.
The L’Universelle went into storage and was then destroyed.
Its overall shape was later reflected in the rear-engine Greenbrier van which was based on the Corvair platform.
