Summary

The 2007 Chevrolet Optra presents a mixed bag for potential buyers. While it offered affordability and decent interior space at the time, it is now an older vehicle prone to reliability issues. Engine problems such as oxygen sensor failure and EGR valve issues are common and can lead to drivability problems. The 4-speed automatic transmission is also known to have issues, especially with harsh shifting and slippage, potentially requiring costly repairs or replacement. Suspension and electrical problems further contribute to the overall ownership cost.
