All the windows were seriously blacked out, including the windshield. On the interior, the car had a carbon fibre steering wheel (where the top and bottom portions were ALSO carbon fibre), in addition to the spokes. It was gorgeous.
We were told that the wheel portions would be offered separately from the standard interior Carbon upgrade - so you could (if you want) stick with an Aluminum interior and yet have CF on the steering rim (but the wheel would still have silver spokes)...
Otherwise, the interior was right off the standard options list (Leather/Alcantara with a contrast stitch line)...
