Was checking out the Outback forums and seen this thread. Just thought I'd let you guys know that these work for the GTI too. The gf and I are looking at getting one, since it fits both cars. And then just packing it in the car we take that trip. Check out both links. The first links just to show you all the cars it fits. The second shows better thumbnail pics of the interior size you can click on for different angles.
