Breakfast of Champions, by Kurt Vonnegut, Jr. (1973)
Kilgore Trout, little-known writer (who is sane, despite what many people might think) is heading towards Midland City, where he will meet up with Dwayne Hoover, deranged Pontiac dealer. This is their story, told in an interesting narrative, that comments on many aspects of everyday life in an amusing satire.
