Joel Rosen did state in an interview that about 500 cars were built. Motion was stopped from building cars for public highway use in the USA in 1974 by the US Gov. From what I hear, the EPA was going to fine him $5000.00 for every air pollution control device he had disconnected. Some type of settlement was reached where Motion agreed to stop selling the cars. Motion continued building race cars, show cars, export cars and did some custom body work cars with Motion graphics in 1984. Some Motion cars did end up on the street after 1974 where the owners may have ordered them as race or show cars or some type of other arrangement to get them built.
