Most definitions of a production car require that they are mass produced rather than made to order as well as being an original design rather than an aftermarket mod of a production car. I'm not sure of the exact sales model of the Atom 500, but wikipedia says it was a limited edition with only 25 made. Calling it a production car would be generous.
