1. LLtek mats are contoured and seem to give better coverage. Although all I've seen of the Audi ones are pics on Audiworld. But that's my impression.
2. I'm not sure I want rubber mats. We don't have the same wet snow issues that you guys in the East have. Out West, we don't get big wet dumps and have tons of salt so the mats don't get soaked. (Although as soon as I write this the skies will open up and dump,not a bad thing mind you).
The difference in $ is $10 right now as LLtek has free shipping until the end of the month.So I think for a better product for my needs I'll go LLtek.
Now I'm on the prowl for a back mat for the Avant.
LLtek and the Audi Custom and Weathertech are in the running.

the Audi rubber mats stay in place but they don't cover the carpet area as well as the LLTEK

I'll save them for Summer when I don't need the protection as much.

and they work great here in toronto and london (ontario). they never get so soaked b/c they are think....the contours keep everything in place and they have never shifted around on me.

they work great and plus i like the look of fabric over rubber for the mats....rubber mats are a truck thing in my mind. :)

I have them. The mats cover more than the OEM mats and have the rubber backing that prevents moisture from seeping through. It is also shaped and acts almost like a pan.

The fronts fit really well however, the back is another matter. There are gaps from a crease at the edge when the mat is held in at the mat clips. Overall I'm pleased with the mat.
