The 1972 MONICA was an elegant concept luxury-performance sedan from a colaboration of French & British engineers which never got off the ground and only a few models were ever assmebled.
The vehicle's cat like lines and dual sports/luxury character will ultimately be realized in a production car 36 years later when the new Porsche Sedan is brought to market next year and fighures to look like an update version of that car.

As you can see Porsche had already borrowed the front end styling for it's 944 (as did Mazda's RX7) while elements of the rear end styling was later appropriated by the Jaguar XJS coupe.
