we can go to betandwin....and make some bets.

10 to 1 that the "standard" audio and climate controls are similar to....(in this pic is the navigation system)
Buick Lucerne......

Pontiac Solstice...
Saturn Vue.....with Cadillac Steering(how many will cost this steering with the Saturn badge and how many with the Cadillac badge???) Also can have the same audio as the Pontiac, Buick.......
Saturn Aura Concept(as you know in the future the Saturn would have many synergies with Opel, the Aura is a good example, mix of Astra and Vectra design)
that's the FORM FOLLOWS THE FUNCTION, by Saab, ok.....big added value by Saab, only you will take car about it when you purchase it as an accessory , When I see that i remember the Bob Lutz words about Saab and synergies, that nobody will take a look under the dashboard to see if the Saab parts woulde be the same as the Opel, the big differential would be in the design of the dash, exterior and so....
if you take a look at the Pontiac G6, it has another type of Audio and climate controls that are commonly used in other GM models. It seems that GM purchase 2-3 differents versions of audio and climate products, spread in the GM model range as you spread corn to the chicken......
I hope that's a transition time for Saab........We see that Saab has a powerful engineering, GM opened some expertise centers in there, its time to give Saab the opportunity to add value to its models and not only to GM models....
