TURBOSPRINT PT-200
 
 
 
Non UK ebay sites bring up all sorts of treasures - not least this PT-2000 Monza for the Italian Market. 

 
 
I'm suggesting both the green Porsche and the white Corvette were the supplied cars but it's highly likely these were substituted with stock fluctuations.

 
 
The box art is a long way from the excellent UK packaging, using photos from contemporary Group 5 Racing.
