 Designed by Antonis Volanis, the Rancho was based on the pick-up version of Simca's popular supermini, the Simca 1100, using its front structure and a stretched chassis.The rest of the body was made by Matra from fibreglass and polyester, including the mouldings adorning the body, which made it look more "sturdy".This technology would later be used on the Renault Espace, Europe's first MPV, which was manufactured by Matra.
