This film, one of the favorite cartoons of John Lasseter, provided inspiration for the animators of Cars (2006). In particular, both films place the car characters' eyes in the windshield (making them more expressive), instead of the headlights like most other animated cars.
This is a sentimental little story of a blue car that is so cute to start with, but which suffers from what all cars do. She begins to age and to rust and to fall apart. It is also a story of identity. But in the end, it is youth that takes over, giving her a new lease on life. It's about second chances and the love that creates them.
