[s-cars] Cargo liner for B5 S4 Avant?

[tom at tomwintermedia.com]

I'm looking for a plastic or rubber cargo liner for a B5 S4 Avant. Done the
google and amazon searches, and seeing a lot of Weather Tec stuff.

Anyone have any experience with fitment for the B5 Platform or any other
suggestions? I don't want a "cut to fit" solution but rather something that
is made and fits out of the box.

Liner must also be waterproof as I'm a skier and wet gear goes back there.

Thanks in advance for the help and suggestions.
