Since there will be no Saab in the game you can stop dreaming about it. I personally love saab, my brothers 9-3 Aero Hirsch rules, but the fact is it will not be included in the game...
We will just have to be happy that Volvo is in, and it´s all thanks to a friend of mine who is the person that got Volvo into Gran Turismo 4 ! (yes, really)
