The Mitsubishi Eterna Sigma was a common sight on New Zealand roads in the 1980s. Known for its Japanese reliability and relatively luxurious appointments, it was often chosen as a company car. This wiki provides helpful information for owners regarding maintenance and potential issues.
Owners often see automatic transmission problems (especially in early models), rust formation in typical Japanese-car locations, and issues stemming from the EGR valve leading to rough engine running, generally arising between 150,000 - 250,000 km.
