Most concept cars live and die inside a design studio. A show car does its one lap on a turntable in Detroit or Geneva, gets photographed under studio lights, and then disappears into a manufacturer’s vault where it’s rarely seen again outside an anniversary press release. A handful buck that pattern every year, and right now there’s an actual, drivable itinerary for seeing several of them in person, no press credential required.
Eight GM Dream Cars, Reunited in Michigan
The Gilmore Car Museum in Hickory Corners, Michigan is currently showing eight original General Motors Motorama “Dream Cars” from the Joe Bortz Collection, on display in the museum’s Heritage Ballroom through March 2027. The lineup includes the 1953 Buick Wildcat I, the 1953 Pontiac Parisienne, the 1954 Pontiac Bonneville Special, the 1955 Chevrolet Biscayne, both a roadster and a sedan version of the 1955 LaSalle II, the 1960 Pontiac X-400, and the 1964 Pontiac Banshee XP-833, a low, needle-nosed roadster that never reached production under its own name.
These aren’t replicas. GM built its Motorama show cars between 1953 and 1964 under design chief Harley Earl to gauge public reaction to ideas that were, at the time, years ahead of anything in a showroom. Most were supposed to be scrapped once the tour ended. Collector Joe Bortz spent decades tracking down the survivors, and GM Authority reported that this is the first time this particular group of eight has been displayed together under one roof. The exhibit is included with general museum admission, and Harley Earl’s grandson, Richard Earl, gave a lecture on the collection when it opened in April.
Turin’s Heritage Hub Keeps Its One-Offs on Public View
If a trip to Italy is on the table, Stellantis runs a permanent facility built specifically to keep vehicles like this accessible rather than locked away. The Heritage Hub occupies a restored Fiat mechanical plant in Turin’s Mirafiori district and holds more than 300 historic vehicles and prototypes spanning Fiat, Lancia, Alfa Romeo, Autobianchi, and Abarth. One dedicated section, billed as “Concepts and Fuoriserie,” is set aside specifically for rare one-off show cars and prototypes that never went into series production. The museum is open Tuesday through Thursday for self-guided visits and Friday through Sunday for guided tours, with tickets sold online, so it functions less like a rotating exhibit and more like a standing archive a reader can actually walk into.
Stellantis also keeps pulling individual pieces from that collection out into the public eye during the year. In late September, three Lancia cars connected to the brand’s partnership with Pininfarina head to the Piedmont region for Festival Car 2026, on display at stops including Castello Cavour in Santena, which gives anyone touring Northern Italy this fall a second reason to route through the region beyond the Heritage Hub itself.
The Petersen Still Has a Floor Built Around Concept Design
Back in Los Angeles, the Petersen Automotive Museum’s official floor guide lists a standing gallery, 3.3 in the Audrey and Martin Gruss Foundation Gallery on the third floor, labeled simply “Concept Cars and Art.” It sits apart from the museum’s rotating temporary shows, which currently include a retrospective on 25 years of “Fast & Furious” vehicles and a survey of Aston Martin history, both detailed on the museum’s current exhibitions page. Because the Petersen swaps its featured shows several times a year, the gallery guide and exhibitions list are worth checking right before a visit to confirm which specific cars are on the floor that week.
Worth Checking Before You Go
None of these are guaranteed to stay exactly as described for the rest of the year. Museum loans move, cars get pulled for restoration, and touring pieces like the Lancia trio headed to Festival Car return to storage once an event wraps. What doesn’t change is that concept cars, despite their reputation as one-and-done curiosities, keep ending up somewhere a paying visitor can stand in front of them. Gilmore’s Motorama lineup runs for the better part of a year, the Heritage Hub is a permanent institution with regular public hours, and the Petersen keeps concept design as a fixture of its layout even as the specific cars in front of it change. For anyone who has only ever seen these machines in old press photos, that’s a rarer opportunity than it sounds.
