Despite Danny DeVito and Brooke Adams' scenes having been deleted, there are copies of this film that exist with their scenes still in place, mostly having been shown on local TV stations in the 1980s or on bootleg copies.
Even though Danny Devito's scenes were cut from theatrical release you can still see him in the "Kenny meets Marsha" scene. If you watch behind "Kenny" as he is approaching the office and the intro to the "I Wanna' Get Next to You" starts you will see Devito's back as he appears to be storming off from a woman and slaps a newspaper vending machine on the way out of view.

The main location of this film was an actual Los Angeles car wash, the Figueroa Car Wash, in Westlake, a few blocks from McArthur Park.

When it was open after the release of this movie, its marquee declared its involvement as a location in this major motion picture.
Richard Pryor: As Daddy Rich, head evangelist of the Church of Divine Economic Spirituality. Though Pryor has been frequently top-billed in promotional materials for this movie, his appearance in the ensemble of performances is only a cameo. Pryor has said in his auto-biography 'Pryor Convictions and Other Life Sentences' that he felt that the public were misled into believing that he had had a bigger part in this movie. Pryor also admitted being high during the shoot by saying: "On the set of 'Car Wash', I was too coked out to know any better".
