📚 Vehicle History

Holden Context:

Holden, an Australian automotive manufacturer, often rebadged and locally manufactured vehicles from its parent company, General Motors (GM), including Opel models. The Astra G was Holden's version of the European Opel/Vauxhall Astra Mk IV.

Platform Origin:

The Holden Astra G is a rebadged version of the third generation Opel/Vauxhall Astra (internally codenamed Astra G, and referred to as Astra Mk IV in the UK). It replaced the Holden Nova and was a significant step forward in design and technology for Holden's small car offering.

Manufacturing Locations:

Primarily manufactured in Europe by Opel/Vauxhall. Holden imported and sold these vehicles in Australia and New Zealand.

🏆 Awards & Recognition

Model Reception:

The Astra G platform was generally well-received for its improved refinement, ride comfort, and handling compared to its predecessor. While specific awards for the Holden Astra G in Australia may be limited, the European models often received praise in their respective markets.
