Never saw it but there was a 1972 novel by Harry Crews called Car.
Synopsis:
The main character in “Car” by Harry Crews is Herman. He is at once a fun loving and yet rebelling against the car. Herman decides upon the ultimate adoration and ultimate sacrilege. He will eat an automobile from bumper to bumper. His inspiration is seized upon by a local hotel operator, who turns his establishment over to this historic event. A ballroom is set up for some daily performances. A coast to‐coast television contract is signed and a satellite hookup to Japan arranged.
I remember that book. I read most of Crews’s novels back in the 80s. He was a strange one.
