S/n 0393GT was the last of the series and the only with a different body style. Instead of a short rounded rear portion, it featured prominent double-stepped rear fins, reminiscent of the 375 MM Pinin Farina Coupé Speciale s/n 0490AM. The car was displayed at the 1955 Paris Motor Show, and after the show was sold to a Parisian André Dubonnet. For the 1956 edition of 24 Hours of Le Mans, it was registered to race with Michel Dubonnet and Maurice Trintignant, but they failed to appear.
