Opel Insignia is already available in China as Buick Regal (earlier post) and soon, it will head to the States. Following the same pattern, the all-new Opel Astra will be sold in China as the new Buick Excelle... and it is very likely that it will be made available in the States as well.
The first photo is the official teaser, while the other ones are some spy photos providing a clear indication of how the actual car will look like.
