I'll be ordering one of those too when they're available.
My only concerns are the tools and skill levels required to neatly cut the body panels as its not the usual big hole with an even bigger piece of plastic to cover it. I think it would need a very detailed set of instructions and diagrams to make it a DIY proposition.
I would also be very interested in the routing within the engine bay, the RHD models in the UK and here in Australia are laid out slightly differently to the US style LHD models
