I worked at the dealership where Clark purchased the wagon as a mechanic for 12 years I REMEMBER IT TOOK ALL DAY TO SHOOT THAT SCENE. If you look in the back ground inside the service entrance i was working on that black Dodge step side pick up. It needed a distributor rebuild. The filming crew fed us that day. Catered lunch.
