Description

Our team recently completed a comprehensive restoration of this rare 1950 Jaguar XK-120 Alloy Roadster, and the Jaguar has since enjoyed an exceptional 2026 concours season! It has achieved three separate perfect 100-point scores in JCNA-sanctioned competition, officially qualifying it for JCNA National Champion status. The Alloy will be recognized with its National Champion award at the Jaguar Clubs of North America’s Annual General Meeting in 2027. Most recently, it earned 100 points, first place in the Champion Division C2/120 class, and co-Best in Show at the San Diego Jaguar Club Concours d’Elegance in July of 2026.

The restoration was completed to show-level while preserving the XK-120’s authenticity and historical character. The roadster was stripped to bare metal, carefully fitted and metal worked, then painted, color sanded, and buffed to a concours-level finish. Its original mechanical components were preserved and serviced, while the interior was completely retrimmed in correct materials by our master trimmer.

Only 242 Alloy-bodied XK-120s were produced, including this numbers-matching example, chassis number 670121, one of just 184 left-hand-drive cars. It retains many distinctive early features, including chromed top bows, chromed seat bases, taller SU carburetors, steel disc wheels, and rear spats. The car also has an impressive history, having been owned by a noted Jaguar collector in Switzerland, where it participated in rallies and shows, before later coming to the United States and completing events including the Colorado Grand.

After Classic Showcase reacquired the Roadster, Tom made it his goal to return the XK-120 to its original glory. Guided by its Jaguar Daimler Heritage Certificate, the restoration was completed to reflect its original factory specifications, including its original exterior and interior color combination. Following the restoration, the Alloy became Tom’s personal Jaguar and has since been shown and enjoyed by him at concours events throughout the 2026 season!

Today, the XK-120 stands as an exceptional example of one of Jaguar’s most significant early sports cars, combining rarity, provenance, authenticity, and a proven concours record. It comes complete with its Jaguar Daimler Heritage Certificate of Authenticity, tool roll, tools, jack, and owner’s manual.

History

While most contemporary observers of the Jaguar XK120 would be certain that it was born for greatness, it is surprising to consider that it was conceived and born as a limited-edition stopgap model. William Lyons assumed that the post-WWII fortune of his company, the recently re-named Jaguar Cars Ltd., would be made on the saloon cars that would sell so well in export markets, especially in the U.S. To that end, a new dual overhead-cam, six-cylinder, 160 horsepower engine was developed to power a new luxury sports four-door. As the new car was not yet ready, it was decided to launch the engine in a limited run of alloy-bodied roadsters. When shown at the 1948 Earl’s Court Motor Show, it created a sensation. Following a speed run on a Belgian highway in 1949, in which an XK120 ran 126 mph with its windshield on and 132 mph without, there was no doubt that this would become a regular production model. After 240 alloy cars were built, production was shifted to more easily manageable steel, which was now more widely available following post-war material shortages.
