Besides, their GM trucks, Is Cadillac the only car division still holding GM together?

I know that Cadillac is not like it used to be anymore so far as to being a reliable vehicle and one of the top luxury vehicles to have.My grandmother still has her 17 year old 1992 Cadillac Sedan DeVille with a 143,000 on it which she brought brand new. When she takes it in to get a oil change or a tune up, the mechanics tell her that her car was one of the last models of cadillacs with the northstar system made with a good engine. but the years after that they have just seemed to have gone down hill. I personally still love Cadillac`s and still plan to get one, one day. but since GM is on this bail out besides their suv`s and trucks it seems that Cadillac made up most of GM sales. but i am not saying that this is %100 true. Pontiac`s are nices, but i don`t see them on the road much anymore although they are not my style i do like the new 2009 G8, Chevys have always been a little boring to me except the Corvette! I have always hated Hummers even when they first came out, Saab's are in a world all by themselves i do like the 2009 9-3, and Lest not forget the Buick's that Tiger Woods was advertising and the only model i had considered at one time was the LuCerne. but i don`t see a lot of them on the road. my co-workers daughter just brought a Enclave, and she says she love it, but that car i don`t see it on the road.And before GM killed Oldsmobile I liked the Aurora eventhough it had a strange look to it. it was something different to look at kind of like when the Infinit FX 35 came out it was something different to look at.really the only GM vehicle that i still quiet a few of them on the road is Cadillac.but once again i not saying that even the Sara Palin`s mini-vans did not contribute to some of GM. but i hardly see any of them on the road either.please tell me your thoughts.
