Visible crew/equipment: When Kimble gets into the cab, the vehicle's shiny yellow side captures a reflection of the entire camera crew. (00:26:45)
Continuity mistake: Kimble walks out of Jean's apartment, leaving his bag behind. But in the very next shot, he's holding the bag as he comes out of the building. (00:48:25)
Death Is the Door Prize - S4-E2
Revealing mistake: Marcia demonstrates an early home video recorder at the trade show. Her camera set-up should record her test subjects from a lefthand angle. But her tapes show them all from a righthand angle - the position of the actual studio camera. (00:15:00)
The Other Side of the Coin - S4-E16
Continuity mistake: Corby hides Kimble in the trunk of his car. When it's partially opened, we see Kimble in a horizontal bar of sunlight. After Corby slams the trunk shut, we see another shot of Kimble, who should now be in the dark, still illuminated by the bar of sunlight. (00:47:20)
Continuity mistake: When Rafe is shot at the end, the gun he was holding in his right hand disappears between shots. (00:45:15)
Answer: Production vehicle models aren't in sync with the calendar year. The '65 Mustang began production in March 1964 and first sold in April 1964, before it was "introduced" the following year. I don't know which model was seen in the episode, but the 2+2 fastback was sold in September 1964. The 1964 film "Goldfinger" uses a 1965 Mustang as part of Ford's product placement. Basically, in the 1930's, FDR ordered automakers to release vehicles in the fall of the preceding calendar year "as a means of facilitating regularization of employment in the industry." Now, automakers can release new models as early as Jan 2 of the preceding year.
