Hi
I got one from Boot Buddy - and since the lease is up on my X - its up for grabs if you are interested. You can see it on the Boot buddy.
I also had a rubber liner mat (the hard liner is slippery - the neoprene type mat makes it grippy. And I had the base in two parts - so I could get to the trunk under more easily - I had a dog crate strapped in so to remove it to get o the oft used cavern of the under trunk was too much without the separate access.
