Bitter

Bitter is a German niche automobile brand founded by former racing driver and entrepreneur Erich Bitter in the early 1970s. The company became known for producing hand-built, coachbuilt luxury GTs and convertibles based on Opel mechanicals, beginning with the Bitter CD (1973) and later models such as the SC and the later reinventions in the 1990s and 2000s. There is limited publicly available, detailed historic information about a formal corporate logo; instead the marque is principally identified by the family name "Bitter" on its cars and marketing, reflecting the founder-centric nature of the brand.
