Greenwood collaborated even more deeply with engineer/designer Bob Riley to create a tube frame chassis for better handling and a narrower body for better aerodynamics.  Only 2 were built.  John Paul Sr bought this one before moving on to a turbo Porsche 935.  It is now in the collection awaiting further restoration by noted racer/classic car dealer/entrepreneur Bruce Canapa from Scotts Valley CA.  More info
