Ive got the Holden one as well for my WN but unfortunately i had to settle for the WM version as thats what available only now
For it to fit correctly i need to trim the driver side off a little (which i haven't still) for it to sit completely flat on that side. Came with the Holden umbrella too.
Besides my fitment issue i absolutely love it and I'm very happy with it.
As users have said on here already its very easy to remove and and be cleaned in a few mins.
I don't have to stress anymore when putting anything in the boot as before id always be worried incase something would fall/spill onto the carpet!
