Founded by former race car driver Erich Bitter in 1971, Bitter specialized in luxurious, hand-built sports cars using reliable Opel/GM mechanicals. Key models were the striking CD (1973–1979), based on the Opel Diplomat, and the elegant SC (1979–1989). The brand is known for blending reliable engineering with exotic Italianate styling.

The Bitter SC was an elegant, German-engineered grand tourer (1979–1989). It blended reliable Opel Senator mechanicals with striking, Ferrari-inspired Italian design.
The Bitter SC model did not have formal "generations" (Mark I, Mark II) but rather introduced different body styles and engine upgrades during its production run: SC Coupé: 1979–1989 (Customer deliveries began in 1981). Engine change: Initial 3.0L inline-six was later supplemented and largely replaced by an optional, more powerful 3.9L inline-six from 1984 onwards. SC Cabriolet (Convertible): 1982–1986 (Very low-volume production). SC Sedan (4-door Saloon): 1984–1986 (Very low-volume production).
The Bitter Type 3, planned as the successor to the SC, was a luxury sports cabriolet based on the Opel Omega chassis. Only a handful of prototypes were built between 1987 and 1991.
The Bitter Type 3 never reached mass production; its history is based on prototypes and limited concept variations. Bitter Type 3 (Prototypes): 1987–1991. Type 3 Cabriolet: 1987–1991 (Four prototypes built, with a facelift shown in 1991). Type 3 Sedan: 1987 (One wooden mock-up built). Related Successor: Bitter Berlina: 1995–1997 (One prototype built; sometimes referred to as the Type 3 Limousine/Type 4 based on the later Opel Omega B)
