The Petersen Automotive Museum in Los Angeles will celebrate “Dream Cars” from the 1950s with its newest exhibit, “GM’s Marvelous Motorama: Dream Cars From the Joe Bortz Collection.” The unique display will open on March 16 and run through March 2026. The exhibit will feature six concept cars, displayed initially at GM Motorama shows in 1953, 1954, and 1955.
Staged 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. Some of his creations were put into production, including the 1953 Corvette.

“These cars are the Picassos and Rembrandts of this automotive generation. To see six of them together, all from the ’50s, and all the real deal is a once-in-a-lifetime opportunity.” — Joe Bortz, collection owner
The Marvelous Motorama exhibit will feature six cars, including three rescued from near destruction at Warhoops Auto and Truck Parts in Sterling Heights, Mich. After their time in the spotlight, most “Dream Cars” were sent to scrap yards to be cut apart and crushed. Four cars were saved by Warhoops employees and squirreled away among junked car bodies. After hearing rumors about the saved “Dream Cars” in the mid-1980s, collector Joe Bortz purchased the four cars from the scrapyard.

6 Motorama Cars On View
Museum visitors to the Marvelous Motorama display will see the 1955 LaSalle II Roadster and 1955 Chevrolet Biscayne, which Bortz painstakingly 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 wholly original and unrestored 1954 Pontiac Bonneville Special.
“These cars are the Picassos and Rembrandts of this automotive generation,” said Bortz. “To see six of them together, all from the ’50s, and all the real deal is a once-in-a-lifetime opportunity.”

“Joe Bortz has an incredibly unique collection of historic cars, the likes of 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.”
