I just saw a new GM commercial for "total confidence". The tag is "vehicle value protection when you buy your next GM vehicle." Who knows if this is a good idea or will "work". That's not why I mention it.
I mention it because halfway through the commercial they add "excludes Saab" at the bottom. What does that say about Saab? What does that say about GM?
What's your exception, and why do you really need it? Maybe the exception is pointing to something you need to fix.
