Thanks everyone. I have used the Hatchbag items on several cars in the past when I had a mucky Spaniel who loved to walk in the forest. They are fantastic products. Don't think I need anything so extreme now as my current dog is a much "cleaner" Labrador who will hardly walk through a puddle.
I haven't got my GTD yet, can someone explain about the high and low level of the boot floor and how this affects the boot mat.
The Amazon one does look good as I had noticed it on Ebay as well. Anyone any pics of the genuine VW items and how much are they? Do some of the genuine ones have a bumper protector?
