The Plymouth Sapporo was introduced in 1978 as a corporate cousin to the Dodge Challenger. They both were imported from Mitsubishi.
Like the Challenger, the Sapporo received 1.6L and 2.6L I4 engines through its lifespan. Shifting duties were handled by either a 5-speed manual or 3-speed automatic. The final year for the Sapporo was 1983.
