Did Cadillac make a truck similar to the Chevy ELcamino have been told they did never saw one has anyone?

In 1954 General Motors produced the Cadillac El Camino, a drivable show car to be displayed in the 1954 GM Motorama. It was not a car pickup in the same vane as the Chevrolet El Camino, and had no rear bed. It was instead a 2 seater car that was never put into production. Chevrolet also used the El Camino name on a true pickup in 1959.
