Maybe Saab automobiles will be re-married to Saab Aircraft? I don't know about Opel's currents sales, but over the past 40 years, Opel has been a HUGE money maker for GM.
GM also announced discontinueing Saturn after 2011. Most of the Saturn dealers are banding together to attempt to "sell" themselves to another make trying to enter the USA....namely, China or India. GM might agree with that, because when they killed Oldsmobile, it cost them a billion dollars to pay off the dealers who throats they had just cut.
