It was an open-top vehicle with a lower windscreen and a roll bar at rear painted in the colour of the body of the car.

It bears a striking yellow paint scheme and eatured hydraulically operated butterfly doors and pop-up headlights.

The Iguana concept car, designed by Italdesign Giugiaro, was presented at the Turin Motor Show in November 1969.

The body of the Iguana was painted a metal-flake grey, while the roof frame and cabin pillars were finished in brushed metal, a treatment Giugiaro later applied to the DMC DeLorean.
