Thanks to all on the forum who have responded to my hopefully not too daft questions so far......

I have just ordered the following:

A6 Avant 2L Ultra S line S tronic
Misano red with black pack
Alcantara/leather seats
Heated front seats
Fine grain ash inlays
Lighting pack
Speed limit display
Technology Pack Advanced

Although I've never been a fan of privacy glass, having looked at it on the Audi Configurator webpage combined with the misano red and black pack it does seem to suit it very well!!!

However, I'm a bit concerned about how much darker this will make it inside, particularly for the back seat passengers. How much darker will this make the interior, since I'll already have black seats and headlining etc.? Does it also make everything outside appear darker for the rear seat passengers?

Are there any other disadvantages with privacy glass - except for another £390!

Also, given that the FL cars have the acoustic glazing, I assume this won't impact on this since the former is just on the windscreen/front windows whereas the privacy glass is on the rear windows?

Thanks again.
