When The Sheik is with Ponch and Jon at the traffic accident, the Cadillac ambulance reads F&B. This is an ambulance from the movie "Mother, Jugs and Speed."
In his "that's Shah business" joke, Ponch refers to Mohammad Reza Pahlavi, the Shah of Iran (1919-80), who ruled Iran from 1941 until his ouster in the January 1979 Revolution, which took place only two months after this episode aired. The Shah's monarchical government was abolished and Iran then became an Islamic Republic ruled by Ayatollah Khomeini (1902-89).
The red sports car that Ponch and Jon chase is a Dino 246. Although built and sold by Ferrari, it was never given the Ferrari name, as it had a V-6 engine, and only cars with V-12 engines could be called a Ferrari. (This policy would change soon after that when they introduced the 308 model.) Also, a sky blue Maserati Merak can also be seen on the highway during the chase scene.
In this episode, Jon Baker shows off that he can speak French.
