A Clean and Quiet Town - S4-E3
Continuity mistake: The rear tires on Kimble's car get stuck in the sand and spin when he's trying to U-turn and avoid the roadblock. After the police order him to drive back to town with them, however, the car wheels somehow unstick themselves, and Kimble has no trouble at all driving out of the sand pit. (00:48:25)

Continuity mistake: The one-armed man, whose name was earlier established to be Fred Johnson, is for some reason re-named Cramer in this episode's credits. (00:49:40)
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.
