I just had a real quick question: The gel in my passenger side mirror is starting to creep up and fail and I'm looking at replacing it. I see a regular mirror and then one that's for the premium/ultra luxury package. Since it's auto-dimming -- which I now couldn't imagine NOT having -- does anybody know which one is which? Can these cars NOT have that feature? I defer to the experts...
