This phenomenal model is truly a work of art and coupled with the finest electronics at the time of manufacturing, it is unparalleled in quality. Some of the many features of this model are a synchronized cassette tape that coincides with the functions of the car; the lifting of the funny car body, firing sound of the engine, which features flashing header pipes and spinning blower belt on the engine front. The only flaw is no Spinning tires, but wheelie action, count down lights on the starting line tree, all work. So many features and actions all working at the same time, and the ability to repeat these actions for continued demonstration. The base unit requires 4 ‘D’ cell batteries for operation.
