Imagine building one of the most extravagant concept cars of the 1950s, showing it off to millions of people, and then sending it to a scrapyard. That’s exactly what General Motors did with the one-of-a-kind 1956 Cadillac Eldorado Brougham Town Car.
Fortunately, the Cadillac escaped its intended fate thanks to a scrapyard owner who couldn’t bring himself to destroy it. Nearly seven decades later, the remarkable survivor has sold for $494,500 at RM Sotheby’s 2026 Hershey auction in Pennsylvania.
Known internally as the XP-48, this extraordinary machine was created for GM’s 1956 Motorama exhibition. It was designed by Robert Cumberford, who was just 19 years old at the time, working under Herb Cadeau and legendary GM design chief Harley Earl.
Today, it stands as the only 1956 Eldorado Brougham and the earliest surviving example of Cadillac’s famous flagship. Few concept cars from GM’s Motorama era have survived, making this Cadillac an exceptionally rare piece of American automotive history.
A Cadillac Fit For Royalty
The Eldorado Brougham Town Car was designed to demonstrate just how luxurious a future Cadillac could become. Its handcrafted fiberglass body featured an open chauffeur’s compartment, an enclosed rear passenger area, and a glass partition separating the two.
Inside, passengers enjoyed black and beige leather upholstery, Wilton wool carpeting, gold-finished hardware, and air conditioning. Cadillac even included an intercom, a cigar humidor, drinking glasses, and a thermos, although the latter turned out to be a nonfunctional display prop.
The Town Car toured the United States during the 1956 Motorama before making an appearance at the Paris Salon later that year. Wherever it went, the futuristic Cadillac attracted attention, often accompanied by a model wearing Christian Dior.
Saved From The Crusher By A Wedding Dream
In 1958, GM shipped the Cadillac to Warhoops Used Auto & Truck Parts in Warren, Michigan, alongside three other experimental vehicles. The cars were intended for dismantling, but scrapyard owner Harry Warholak Sr. had other ideas.
While the other concepts were partially dismantled, Warholak kept the Cadillac largely intact, hiding it first in a trailer and later under protective covering. According to his son, he hoped to restore the car for use at his daughter’s wedding.
That wedding plan never materialized, but Warholak’s decision ensured the Cadillac would survive long enough to be rediscovered by collectors. Collector Joe Bortz eventually acquired the Cadillac and the three other GM concepts from the Warholak family in 1989.
From Forgotten Show Car To Award Winner
The Cadillac subsequently passed through the hands of several prominent collectors, including J.C. Whitney owner Roy Warshawsky and Cadillac enthusiast Dick Baruk. Warshawsky began a major restoration, which Baruk completed after acquiring the vehicle in 1996.
Interestingly, the original show car wasn’t built as a fully operational automobile. GM had omitted a functioning drivetrain and several essential systems, instead adding weight to the front end to give the Cadillac the correct stance.
During restoration, a period-correct Cadillac V8 and transmission were installed, along with dual four-barrel carburetors and gold-plated valve covers. The work allowed the Town Car to move under its own power at exhibitions, although it was never fully engineered for normal road use.
The restoration eventually earned the Cadillac Best in Class honors at the 2013 Amelia Island Concours d’Elegance. Its remarkable history and distinctive design have helped establish it as one of the most fascinating survivors of GM’s Motorama era.
Nearly Half A Million Dollars Later
At RM Sotheby’s Hershey auction, the Cadillac changed hands for $494,500, a considerable sum for a car that GM once considered disposable. It’s an extraordinary turnaround for a prototype that spent decades hidden in a Michigan salvage yard.
Whoever bought it now owns a genuine piece of Cadillac history, complete with an almost unbelievable backstory. Not bad for a car that was once supposed to end its days in the crusher.
