Mannix drives two different 1974 Camaros. For most of the episode the car he drives is a standard, blue Type LT. When he escapes from the Juice Man's hoods he is driving a blue Type LT with bright trim that extends from over the doors and on to the "B" pillar.
It is an obvious stunt double for Mannix that is proceeding down the red steps of the Kert Mansion where a man lies in wait to ambush him.
When Mannix is allowed entry into the Kert mansion and he walks back to his car, the cables for the film equipment are visible hanging over the exterior wall.
