Here are some copy cat cars. Vauxhall Astra - Opel Astra - Saturn Astra - Holden Astra. -------> First Made. Vauxhall Astra. Second Made. Opel Astra. -------> Third Made. Saturn Astra. Fourth Made. Holden Astra. With the Vauxhall Zafira there are only a few copy's that other brands had made and that was Opel and Holden and I think Chevrolet as well. These Astra cars look EXTREMELY similar to each other. I have been in the Vauxhall Astra but not the Opel though. Even though that there are some Opel Astra's in my country BUT not the Holden Astra and the Saturn Astra.
