“It Was Fine When I Drove It In” is a humorous country song about a man who takes his paid-off truck in for a routine oil change and tire rotation, only to be handed an enormous list of costly repairs. After leaving the service shop, the truck suddenly develops clunks, rattles, warning lights, and mysterious leftover parts. The song pokes fun at aggressive repair upselling, with the central punchline: he went in for an oil change, nearly left with a second mortgage—and the truck was fine when he drove it in.
