Here are some pics of my black Canvasback liner in my WK2. Note that in some of the pics the liner looks gray due to the camera flash. The black liner is perfect for the WK2's black interior. I purchased the add-on side liners for $20 more.
First pic is my Mopar rubber cargo liner on top of the Canvasback liner.
Here is the Canvasback liner by itself.
Shot of the subwoofer liner.
Shot of the other side liner. This covers up the little pocket but since it's attached with velcro you can easily get to it.
Shot of the seam for the 60/40 rear seat liner.
And finally here's a pic of the logo and to show that you are able to access all the hooks and handles necessary that the liner covers.
The Canvasback liner isn't cheap but I think it adds a little bit of protection for the areas a cargo liner doesn't cover. And since my 2 boxers ride in the back the liners make it a lot easier to keep the factory carpet hair free and clean.
