Saab = Opel…

wg. asked me about a sports-scarf at the dealer (wg. advised me not the turbo – does not sound reasonable) and then I was told immediately that I can actually forget saab, because there is only opel in it, and that is much cheaper with the same performance. now I am a bit disappointed and looking for your opinion. is there really EVERYTHING of opel in it??? that the saab have taken over (gerneral motors) is clear to me, however, thought, they only build the motors for the diesel ….??? what do you think about the statement? saab 9-5 aero mod. 2001 limousine
