Does your driver's side view mirror have a black line around the perimeter? I noticed on the passenger side view mirror it does not have this line. Unless they had some mix up at the factory and put in the wrong mirror. Why have the line on one mirror and not the other?

 

There is a special coating on it that at night auto dims th light reflection I am not sure whats this called.

 

Only driver side mirror has a special coating for auto-dimming function. Passenger side doesn't. Don't worry about it!
