Very Brutal

and I know its old
This was the only Pro-Car that was built for a proposed new series of "Silhouette "racing..
It was proposed that all the manufacturers would field silhouette cars representing there production cars.
Alfa went and built an example based on the then F1 chassis to showcase the looming series.
The manufacturers decided not to get involved and the series never saw fruition..Hence the only Pro-car in the world.
