DanA100

... i don't want to tint my rear window but i want to save my interior from the sun in Cali.
So here is what i need...i don't even know how they call it (help me if you know the name) but i've seen it on many older Audi V8s in my area. It's basically a black sun shade/curtain that is installed on the rear window. It looks like cloth or something simular, very fine and almost transparent. Looks very classy and all new luxury cars (Audis, BMWs, Mercedes) have them. Again, i'm not sure about the exact name.
Where can i get one of these for my car? If they have it for V8 Audis, they should fit on my Audi 100 as well.
Do you know who sells them? Do you know how much they go for? I'm afraid to ask the local dealer.
I really want one of these - it was 100 degrees today, again.
Thanks for any info!
