Interesting they've used the painted Sport dash ( and a left hand drive...the main market?) but I just love that leather!
Looks nice and similar to the Roadster Sport with the "trinket box"/arm rest, and distressed leather, and as you say painted dash and cargo net. But who knows, it's a pre production car; usually it doesn't mean large changes, but since and ad, perhaps some extra equipment.
My first thought, a bit odd given all to look at, was about the speedo, just to the left. They usually put it as far away as possible no matter if LHD or RHD, don't they? Or at least I thought they did, if one doesn't request something special, if possible that is. Had a look at some different pictures, and in the latest 2011 brochure it's next to the steering wheel in LHD for the Roadster Sport, but then in the "fake", i.e. mirrored (since it is a LHD), RHD image of the 4/4 Sport it's on the other side of the instrument cluster. Odd. There are some possibilities, either it's always the same place, and then if it's close or not depends on if LHD or RHD, or, they move it (mirror the dash) so that it is always at the end of the instrument cluster. But my images show both cases for LHD.
Anyhow, around 260 hp should be more than enough to keep everyone focused on the road rather than the dashboard.
