I'm in Love with My Car is a song written and sung by Roger Taylor from the A Night at the Opera album.
The B-side to Bohemian Rhapsody, it is about cars.
The revving sounds at the conclusion of the song were a recording of Taylor's then current car, an Alfa Romeo. The lyrics were inspired by one of the band's roadies, Johnathan Harris, whose Triumph TR4 was evidently the "love of his life". The song is dedicated to him, with the liner notes mentioning, "Dedicated to Johnathan Harris, boy racer to the end".
