Generation:

This generation of Nubira (J100/J150) was produced from 1997 to 2003, with the model years 2000-2003 representing a significant part of its lifecycle.

Manufacturing Locations:

Primarily South Korea, with potential assembly in other countries under license or joint ventures.

End Of Production:

The Nubira was eventually replaced by the Chevrolet Lacetti (known as Daewoo Lacetti in some markets) after GM's acquisition.

🏆 Awards & Recognition

Market Perception:

The Nubira was generally perceived as a budget-friendly car, offering decent value for money in its segment at the time of its release. It was not known for winning specific major automotive awards but was a significant player in the value car market.
