During the interior dashboard view when Rockford was driving the green Volkswagen, the speedometer was always reading "0".
As Jim starts to back up the Volkswagen the crew is visible in the small window near the side view mirror.
When Rockford calls Mr. Moss to report the $10,000 check has been stolen, Moss rebukes him by saying,"You were hired to find Miss Wade and give her the check. You've lost her and the check." Rockford had only told him about the missing check; Moss had no way of knowing that she was also missing.
