C.AR was a Greek automotive company, founded in 1970. Originally it was called ARCO, both names being formed from the name of its founder, Constantinos Argyriadis, an engineer and architect. With its headquarters in Thessaloniki and a well-equipped factory in Kilkis it concentrated on design and development of automobiles and related technologies, including composite materials, novel suspension and brake designs, electric vehicles, etc. None of its vehicles, though, entered production and thus this company represents an odd case of personal vision and persistence with catastrophic financial results.
