The most popular Hot Rod of all time has to be the 1932 Ford 3-window coupe.
The 5-window is not neary as popular, but is still a popular Hot Rod.
The American Graffiti coupe was a fenderless 1932 5-window coupe.
I'm @runridefly, and my uncle spent over a decade building a 1932 Ford, and he had to sell it because of financial hardship.
