I can't believe that this ATS subject is still alive. It's obvious that nobody cares about Cadillacs here.
For me, I got stung with a major engine problem (under warranty) in my ZO6 that now many others are having the same problem (with still no legitimate answers from GM as to why, or if their repairs are long term fixes), and I won't be back to a GM product anytime soon. My '08 Tahoe was one of the last to be built in their Milwaukee plant before they closed it and moved their assembly to Mexico and Texas, and it was also the last of the Tahoes to be trouble free. I will not buy a Japanese (bad experience in the past), Korean or Chinese car because they are souless to drive, and IMO, most are just cheap clones of European cars. So, that leaves me with European cars which includes BMWs.
