 CONT: When Cobra is chasing Slasher down the alley way, as they  approach the end we can very clearly see the rear of Slashers car.  Specifically, the bumper bar is dragging along the pavement. In the  next scene, and for the remainder of the car chase for that matter,  the bumper bar is attached. At the same time, the car (a 1979  Plymouth Volaré) is seen with a front grille during the alley scene  although the passenger side fender was bashed in one scene (in  subsequent scenes, the fender is undamaged). The overall condition  of the Volaré changes frequently (in some scenes, the car has all of  its front lighting missing to one headlight and one park lens).
