Don't know what he's on about to be honest - the parcel shelf itself is of a roller-blind design.
Take a look at the black plastic mouldings at the top of and behind the rear seats: if there are a number of curved triangular holes there, you have all you need to fit the parcel shelf I referred to in the Ebay listing.
Just to confuse matters, there is a separate roller blind available for the A2, which covers the rear window.
If it's a parcel shelf you need (and not the false floor) then get the Ebay item - it's all you need.
Cheers,
Mike
