khansen30 - I was figuring that the Astra and the older VUEs, Ions and SC/SL cars that were pretty Saturn specific (not sure how many of them are still warrantied) were the reason for training. As you stated there really is no difference between the Outlook and the other GM cars that share the Lambda platform. But I'm just relaying what I was told. As far as the the Caddy dealer being snooty - that's possible

. But they also sell Chevy and Honda at the same dealership. Maybe they just don't want to do warranty work...
Interesting side note - using the link that you posted, only the Chevy dealer that I went to comes up as an authorized service center. I know that there are at least 5 other GM dealers in the 25mile search area that don't show up as authorized service centers. Shouldn't more show up if they were authorized?
