The spectacular fiberglass “Corsa Spider” concept car was unveiled at the Geneva Motor Show in 1982. Cover plates were used to complete the transformation from a four-seater to a two-seater.
In the same way, covering the front passenger seat gave the Spider the look of a single-seat race car. Much to the dismay of many fans, Opel did not put the “Corsa Spider” into production.
