I was coming home last night after a little road trip and heard a commercial for a Chevy dealer in Worchester, MA. They were advertising the new Chevy Aveo and at the end of the commercial, they mentioned that all new Chevys have their lifetime engine warranty. Thats pretty bold statement. Has anyone heard of this before? Is Chevy doing this or could it just be the dealer? I would think that a dealer couldn't warranty anything without GM's blessing.
