Waiting for the first generation of Opel Corsa to make its appearance on the international limelight, forty years ago, at the Geneva Motor Show in March 1982, the German house presented the Opel Corsa Spider, a stylistic study of a small cabriolet with a fiberglass body. equipped with the mechanics of the Opel Kadett 1.000 which, due to its external dimensions and many aesthetic features (especially the front), anticipated the sedan that would appear a few months later. A compact sedan, now in its sixth generation, a leading player on the Italian market for over forty years. Among the particularities of the prototype, which was later exhibited also at the Turin Motor Show, is the possibility of transforming it from 4 to 2 seats by simply covering the rear with a special panel equipped with a faired headrest for the driver. The front passenger seat could in turn be covered by a retractable curtain, thus transforming the car into a kind of single-seater. The all-white bodywork and the integral wheel covers were other peculiarities of this prototype.
Contrary to what usually happens with so-called “salon prototypes”, the Opel Corsa Spider had a sequel. In fact, the German tuner Irmscher reached an agreement with Opel to build it in its Remshalden workshops, starting from March 1984 on the basis of the door sedan, produced in the Spanish plant in Zaragoza, which arrived without the tailgate and interior panels in the trunk. To convert them into Spider, the roof was cut in correspondence with the frame of the windshield and the second and third pillars and the various points of the floor and sides were welded.
