Attica was a brand name of vehicles produced by Bioplastic S.A., a company created in Moschato, Athens by Georgios Dimitriadis, an important figure in Greek automotive history. Dimitriadis had designed and built a light four-wheel passenger automobile (model 505) in 1958 with the intent to produce it. A tax imposed on four-wheel automobiles at the time, though, limited the car's market prospects; thus, he abandoned that plan focusing instead on the production of three-wheelers - taxed as "motorcycles" in Greece.
