The 1957 Chevrolet Nomad Wagon, widely known as “Showmad,” is a unique piece of automotive history. This masterpiece was a special “GM Show Asset” (work order W.O. 17792-1c), crafted to showcase Chevrolet’s groundbreaking design and engineering at prestigious events like the 1956 New York International Auto Show, Chicago Auto Show, Detroit Auto Show, and Los Angeles Auto Show. Its unparalleled pedigree and exceptional features make it a standout example of mid-century American automotive ingenuity.
A Rare Showpiece with Prototype Precision
The “Showmad” boasts a fascinating history as a pre-production and prototype display car. Its 283/283 HP fuel-injected V-8 engine is a marvel, featuring polished and chromed components crafted by General Motors’ Experimental Shop. This engine, labeled unit no. 102, is identical to the one displayed on Harley Earl’s desk and seen on the Super Sport Corvette during auto shows. Intriguingly, the unit lacks drilled ID tag holes and casting numbers on the plenum or intake base, emphasizing its prototype nature.
The exterior, finished in an elegant two-tone combination of Larkspur Blue and India Ivory White, complements the interior’s harmonious Black and Blue palette. The car’s close-ratio 3-speed manual transmission further underscores its high-performance credentials, while unique details like a hand-scribed chrome air cleaner assembly and threaded studs for ground straps highlight its show car origins.
Innovative Features Ahead of Their Time
This Nomad Wagon was equipped with cutting-edge innovations designed specifically for its role as a display car. A power switch under the dash allowed toggling between an external power source and the car’s battery—perfect for illuminating the car during exhibitions. Its keys, unpunched from the factory, remain an untouched relic of its assembly. Additionally, thoughtful adjustments such as relocating the voltage regulator and mounting an air intake tube into the driver’s core support demonstrate its experimental nature.
Provenance and Legacy
After its illustrious show circuit career, the “Showmad” passed into private hands, remaining with its first owner, Nathaniel (Phil) Waterson, until it was acquired in 2005 by its second custodian. Over the years, it has been meticulously maintained, restored, and celebrated in publications, further cementing its place in automotive history. Its original California Black plates and documentation from Zora Duntov’s personal records add authenticity and depth to its storied legacy.
