Continuity mistake: During the sequence where Kowalski is being chased through the mining buildings, there's a shot where the passenger-side mirror gets knocked off the car by a jutting pole, and the camera tracks it to breaking on the ground. But the next shot showing that side of the car shows the mirror. It keeps appearing and vanishing for the rest of the scene (when it's not there, there's no sign of damage to the car: the car used for those shots appears to never have had a wing-mirror).
Continuity mistake: The wheels on the Challenger when it bursts into flames are completely different than the wheels during the rest of the movie. During the movie, the wheels are factory Rally type wheels, and the wheels seen while the car is burning are aftermarket Cragar-type mag wheels.
