1984 GM Spain presented a Corsa Cabriolet prototype.
was tried to maintain the original form of the car.
The two-layer roof with a plastic back window was designed that it
could be folded up behind the rear seats. The interior did not
have to be modified and even the folding back seats remained. Due to
the folding roof, the width at the back seats was reduced by a few
centimetres. Thus the Cabriolet was also only laid out as 4-seater.
