I was offered a 3rd party warranty through Zurich. After turning it down twice (2nd time was 50% cheaper than what the original price was) they offered me a cheaper extended warranty through GM that lasted an extra year and 10,000 more miles than what the Zurich one would have covered.

I'm guessing the dealerships make more money off of the 3rd party warranty, otherwise they'd offer the GM warranty up front.
