I was expecting the cover to fit my mirror as I confirmed the car model is a 2017 Mercedes 300 so the size of the cover to be made was correct. This was in response to an email request from Covercraft before the cover was created. However, there is a good 6 inches on each side of the mirror left open to the sun. Another problem is that when removing the cover from the windshield, the outside feels very hot so care must be taken. so as not to burn yourself! The case was also delivered for a very long time. I'm disappointed, especially for such a price.
