Continuity mistake: Toward the end when Crews runs in with Red he first knocks his right headlight out, later it is back in, then it's out again
Continuity mistake: In the scene where the Monte Carlo is battling with the Camaro, they go off road into a field. During a certain shot, the Camaro has to jump a hill and it goes airborne. While it's airborne, you can see the entire front end is destroyed. However, after it lands, you can see the front end of the Camaro is in excellent condition and it remains intact for the remainder of the film. I would guess that they used at least two Camaros for the film.
Continuity mistake: When Swayze first arrives at Red's place, there is a shot of them walking down the length of the trailer. You can see that the legs are already up. He would have had to have been already hooked onto the trailer, but in the next scene, he is hooking up to the trailer.
Continuity mistake: In the shot where the Monte Carlo is about to hit the big rig's rear and is about to explode, look very closely at the side of the Monte Carlo when it is about to explode. The Monte Carlo used in this shot has no visible damage on its side and throughout the car (excluding the front cause it's hit in the shot). Looks like they used two Monte Carlo's for this chase scene.
