Back in the '90s, I saw a light blue metallic 1976 or 1977 Olds "El Camino" at a car auction in San Mateo, California. The car had a matching blue interior and Cutlass Supreme level door, seat, and dashboard trim and claimed to be a factory exercise to test the viability of an Olds pickup. All documents showing the car's history were included. I don't know if the car was real or what happened to the car. I guess if it were a real factory car it would have appeared in Hemmings or some similar publication.

IT POSSIBLE THAT SOMEONE MODIFIED A ELCAMINO WITH A FRONT END OFF A CUTLAS.THE DOORS WOULD NEED TO BE MODIFIED TO MATCH FENDERS I NEVER SAW THE VEHICLE BUT HAVE BEENTOLD BY G M EMPLOYEES THAT PONTIAC HAD A TRUCK LIKE THAT .AND USED IT TO TRAVEL BETWEEN PLANTS .GM WOULD NOT ALLOW IT TO GO INTO PRODUCTION.LEMANS AND MALIBU DOORS WERE THE SAME AS ELCAMINO RAN AUTO PARTS ACCROSS FROM GM PLANT SINCE 1957.
