Most Cunningham automobiles were high-performance prototypes that Briggs Cunningham and his team built specifically for racing in the 1950s. A few, adapted for street use, were personal vehicles. In 1952, Cunningham introduced the Continental C3 road car. Production began in his West Palm Beach plant where his team of mechanics installed 331-cubic-inch Chrysler hemi V-8s in racing chassis. These were shipped to Turin, Italy to be fitted with aluminum and steel bodies by coachbuilder Vignale, after which they were returned to the Florida plant for completion. 25 Continental C3s were produced: 20 coupes and five convertibles. They sold for $8,000 to $12,000. Notable owners included Nelson Rockefeller and a member of the Du Pont family. 24 of the cars are known to have survived.
