The Opel Rekord Series C is a Executive car that was introduced in August 1966, by Opel as a replacement for the short-lived Opel Rekord Series B. It was slightly larger all round than its predecessor, from which it inherited most of its engines. It continued in production until replaced by the Opel Rekord Series D at the end of 1971.

The Opel Rekord Series B is a Executive car that was introduced in August 1965, by Opel as a replacement for the Opel Rekord Series A. The Rekord B shared the wheelbase and 1696mm width of its predecessor, but the front and rear panels were restyled in order effectively to differentiate the new model. The big news was under the bonnet/hood, however.
