When Lieutenant Leaphorn is driving in his GMC Suburban, the steering wheel is obviously from a much newer truck. It is of the four-spoke design that was common during the late 1980s. The wheel is visible when the camera is behind him.
However, when the camera is on the hood of the vehicle aiming towards him, the thin-rim, three-spoke steering wheel is obviously the correct one for a late 1960s GMC Suburban.

At approximately 15:35, Bernadette is chasing someone on horseback. From one scene to the next, the car she is driving changes from a 1965 Impala to a 1966 Bel-Air. Both cars have been seen in the series before, and the assumption was that they were representing two different police cars. This scene seems to confirm that they are trying to make us believe they are the same car. The cars are extremely similar, but there are differences, especially in the front grill and rear taillights.
