I have placed order for GLC43 AMG to be arrived mid-March.

Are all the GLC43 equipped with Acoustic glass? I have asked my dealer to print the equipment list for my car and I found "851 Security Safety Glass with Acoustic Foil for Noise Reduction" as below.

 

I don't know for sure but on Volvos the Security glass option made it harder to do a slash and grab. You can youtube it on the volvo and it shows one guy beating the glass and not being able to break it

 

My build list makes no mention of glass or window type, not even privacy glass or tints even though mine came tinted from the factory.

 

In my order I had the option to put in "Heat/sound isolated glass". Think they were about $300. I put it on because of the 20" wheels!

 

I have asked the dealer and they told me I have to pay $250 CAN, to add the option.
I think it is worth the money. I asked him to include it because I have the 21" wheels!.
