In the second half of the seventies Opel offered the Kadett Aero, a special version of the Kadett C that could be converted in a targa style way by removing the roof panel and folding down the rear end of the roof and windshield.
The Opel Kadett Areo was built at Baur where the Bitter CD was also built. Between 1976 and 1978 only 1341 Opel Kadett Aeros were built.
The idea for this car was originally from Erich Bitter but the car was marketed by Opel. The last 10 cars, however, were all bought by Erich Bitter and were converted to Bitter Super Aeros. They received wider fenders and a luxury interior. The 1.6 litre engine was pumped up to 90 hp.
Somehow the 1978 Bitter Super Areo could be seen as the predecessor of the 1984 Bitter Rallye.
