Me too! I'm interested to know if this can be retrofited.
I tried ordering the Net only, but the dealer told me I would have to replace the whole thing that holds the cargo compartment cover. He was also trying to talk me out of it because he was afraid he might miss out ordering the other bits and pieces (brackets, screws..etc)
Until my dealer learns how to After Sales Service.... my poor 3 x Goldens have to share the little space in the cargo compartment
