Continuity: When they guys in the Impalas are chasing Chevy and his girlfriend from the sweatshop the last car hits the fence. Right before the car hits the fence a guy is hanging out of the window (meaning it's open). After Chevy walks up and finishes the guys off and turns around the angle changes with the car behind him and the window is up. Chevy would have shot it out EVEN IF the guy rolled it up.

Continuity: Chev Chelios drives over to Orlando's hood and enters the Sin City Decibles bar. When Chev pushes Orlando into the bathroom holding a gun to his head, Orlando's thugs enter pointing their guns at Chev. The tall bald thug in the middle has his arm fully extended when the camera is shooting from a bird's eye view, but when the camera switches to a side view he is closer to Chev and his arm is bent, holding the gun closer to his own body.
