During the shootout between the FBI and Matix and Platt, Mike Platt is crouching in front of the brown sedan (in a far shot), but in the very next shot, Platt gets up off the ground and then crouches in front of the car again.
While briefing the other agents in the parking lot, Agent Ben Grogan tells them to be on the look out for a black '79 Monte Carlo. The car the bad guys are in is actually a 1974 Monte Carlo. The FBI would not make this kind of mistake since they questioned the owner of the car earlier and know exactly what year and make it was.
Platt fires twice at Mireles when Mireles is sitting against the car's rear bumper and his shots hit the top of the trunk lid, but there are three bullet holes in it.
