Well, all of the 20 questions have been posed.
The car I was going for (hence my answer above) was 1950 Cadillac Series 61 Coupe. The "right track" connection was because two of these mass-produced cars were sent to LeMans in that year. The team was lead by well-known race car builder and driver, Briggs Cunningham. Two Cadillac's were prepped for the race. One remained basically stock receiving simple modifications such as the addition of a two carburetor intake system, welded-on air ducts for the drum brakes, an extra 35-gallon gas tank in the trunk and simple race equipment such as hood straps and safety restraints.
The other car was stripped to its bare chassis and re bodied by Bill Frick of Fordillac fame at his Long Island, NY shop. He received assistance from aerodynamicists and metal workers from Grumman Aircraft in developing a streamlined roadster envelope. When unveiled at LeMans, this striking body was nicknamed, 'LeMonstre' by the French motoring press. That is the car pieter posted above. Since he was so close, and also posted "Series 62", I'm awarding him a point for his effort.
Of the early post-war Cadillacs, I'd say the Series 61 would be among the most recognizable by auto enthusiasts outside of the States.
