Briggs Swift Cunningham II (1907–2003) made the cover of Time magazine's 26 April 1954 issue because of his effort to build American racing cars capable of winning the Le Mans 24 hour race. As his Wikipedia entry mentions, he did not succeed in winning there, but came close.
In addition to the racing cars, he had to build a number of passenger cars to qualify as a manufacturer in order to compete at Le Mans. Hence the C-3, subject of this post. It seems that 18 coupes and 9 convertibles were built. The Revs Instutute web page dealing with the C-3 in its collection states: "Giovanni Michelotti styled the body; Vignale built it in Turin".
The Cunningham C-3 Coupe was indeed a handsome car whose design was in the mainstream of what I consider the apex of post- World War 2 Italian styling. Because it was powered by a large Chrysler "hemi" V-8 motor, the C-3 was more massive than many coachbuilt Italian cars of the early 1950s. However, Michelotti and Vignale saw to it that it was graceful and not bloated.
