Good analysis, PB.

But I'm betting that the car Michael was driving was an Avis rental. It was a '58 Ford Custom 300, in the exact two-tone red-and-black that was the most popular color combo for that model.
Exactly what Mr. Avis would rent you--Avis was with Ford at the time, Hertz with GM.
The car Johnny Ola's driving is a '58 Chrysler New Yorker. I bet it was Roth's car because that model was
exactly what a wealthy Jew of that era would drive. Both are typical examples of FFC's obsession with authentic touches.
