Hello together, I will order the BiTDI on Monday and am unsure if I should buy the acoustic/damm glass. Drive the “normal” A7 3.0 TDI at the moment, and find that the car is quiet enough, also I do not find the sunlight excessive. Nevertheless, I have read a lot of positive things about it in the forum. What about the extra weight (total) of the acoustic/damm glass (without privacy). Does any of you know about this?
