question : cadelac episode (movie reference)

In the second episode of the two where Jerry buys his parents a cadelac and then they get thrown out of their condominium in Florida, the last scene has Jerry and his parents walking solemnly to the car, the father waving, the other residents waving back and then the three getting into the car and driving away. It is obviously the take off of some movie or something. Does anyone know what movie that scene comes from? Thanks a lot Talya
