New Holden as Omega Successor

While Opel has been waiting for a decent omega successor for years, Australian GM daughter Holden is allowed to develop and build a new mid-size saloon including a new rear drive platform. What has come out of this can be seen quite well here:http://i77.photobucket.com/albums/j70/norbs_photos/4.jpg http://i77.photobucket.com/albums/j70/norbs_photos/1.jpg http://i77.photobucket.com/albums/j70/norbs_photos/9.jpg While the old Holden Commodore even more or less a relabelled Omega, this new model was completely developed at Holden in Australia. Why didn’t they just make a joint project out of it that could also have benefited Opel? Give the car an Opel grill, decent engines and fair prices and zack would have Opel again a chic and especially sporty saloon of the upper middle class.
