Petersen Automotive Museum Prepares for 1950s Concept Vehicles Exhibit

The Petersen Automotive Museum will celebrate “Dream Cars” from the 1950s with its newest exhibit, “GM’s Marvelous Motorama: Dream Cars From the Joe Bortz Collection,” which will open on March 16.

The exhibit will feature six concept cars, together for the first time under one roof, originally displayed at GM Motorama shows in 1953, 1954 and 1955.

Located in the Audrey and Martin Gruss Foundation Gallery, the exhibit will explore the history of General Motors’ traveling Motorama shows.

Legendary GM stylist Harley Earl used the shows to present experimental non-production cars that featured design and technological concepts that found their way to production automobiles. A few models, like the Corvette, went into production.

Six cars will be featured, including three rescued from destruction at Warhoops Auto and Truck Parts in Sterling Heights, Michigan.

After their time in the spotlight, the majority of “Dream Cars” were sent to scrap yards to be cut apart and crushed. Among those preserved were four cars saved by Warhoops employees. After hearing rumors about the saved “Dream Cars” in the mid-1980s, collector Joe Bortz purchased the four cars from the scrapyard.

“These cars are the Picassos and Rembrandts of this automotive generation,” said Joe Bortz. “To see six of them together, all from the 1950s, is a once-in-a-lifetime opportunity.”

Museum visitors will see the 1955 LaSalle II Roadster and 1955 Chevrolet Biscayne, which Bortz restored after both were cut in half in preparation for the crusher, as well as a 1955 LaSalle Sedan in its “junkyard fresh” condition. Additional cars featured in the exhibit are the 1953 Pontiac Parisienne, 1953 Buick Wildcat and a completely original 1954 Pontiac Bonneville Special.

“Joe Bortz has an incredibly unique collection of historic cars, which have never been displayed at the museum,” said Petersen Automotive Museum Executive Director Terry L. Karges. “The Motoramas were an important part of automotive history, and we are excited to share these ‘Dream Cars’ with enthusiasts from around the world.”

“GM’s Marvelous Motorama: Dream Cars From the Joe Bortz Collection” will be on display through March 2026. To purchase tickets or for more information about the Petersen Automotive Museum, click here.
