The model auto racetrack includes a baseboard, at least one component module, component module mounting apparatus, a track module, and track module mounting apparatus. The at least one component module is interchangeably mounted at any position on the baseboard so as to replicate a real racetrack environment and is interchangeable with each other so as to allow the model auto racetrack to replicate any racetrack desired by the user. The at least one component module is at least one of at least one grandstand module, at least one cement wail module, at least one garage module, at least one concession stand module, at least one press box module, at least one landscape module, and at least one fence module.
