Cony cars were built by the Aichi Machine Industry Company in Nagoya. The company was founded in 1943 and in 1965 it became part of the Nissan group. Aichi is still operating today, building the Nissan Serena mini-bus. Cony's speciality was building micro-cars with 2 cylinder engines below 360cc. The under 360cc class in Japan was taxed at a very low rate, making the cars very inexpensive. So the Cony cars took every possible shape, from the sedan to the pick-up, including the break.
For the record, this was their biggest car. They had pick-ups much smaller than this one.
