Andre Denis, from France, based his 500 on a Danvignes sports car frame using transverse leaf springs for suspension. A fan cooled Zundapp KS 600 engine was mounted at the front and drove through a Zundapp four speed gearbox, and then a long propeller shaft to a bevel gear on the back axle, which had no differential. The car was particularly large by 500 standards and failed to achieve any success.

If anyone has any more details or photos of this car, please get in touch.
