The car Syl and Anthony were driving is a copper colored Chevrolet, but in the shot of them driving up to Arrowhead a dark brown or black Ford with a white top is seen.
When Anthony is behind his car and fires his handgun at Rockford in the cabin, the window above Rockford breaks, supposedly from the bullet from Anthony's gun. But when it breaks, you can see a burned mark on the white lace curtain from the explosive charge used to break the window in the scene.
