I toyed with the idea of the water-gray interior. However, the particular color combination that I wanted (Nebula Gray/Water Grey Leather) while theoretically possible, is non-existent in the real world (at least in California). It was actually kind of difficult to track down ANY leather interior. When one came in in Nebula Gray/Black Leather, I jumped on it. Just my experience, but you might be waiting awhile for a water gray interior.
