Saehan Max is correct
A point for you.
Saehan was a joint-venture between General Motors Korea and carmaker Shinjin. In 1983 after ownership changes it was renamed to Daewoo Motor. This car is a 1981 Saehan Max, which was a pick-up version of Saehan Gemini/Bird (a badge-engineered Opel Kadett C). Since 1983 this car was known as Deawoo Max. Curiously, this photo was made in Ecuador.
