Well, speaking of car windows:
When Michael is being driven around Cuba in a '57 Mercury Montclair, the bodyguard rolls up the window when little kids approach the car trying to sell newspapers. But later, when the police stop the car to arrest a guerilla, you see power window controls on the driver's side door.

FFC was a fanatic about details, and that car is an example of perfection: It's in relatively good shape, and has the original cream and turquoise factory paint, but the bumper is kind of lopsided, indicating hard use. It also has a tinny, European sounding horn--exactly what a Latino driver of that era would have added to an American car.
