I think the current blue looks fantastic with any of the available interior choices for the Model S. If you are getting grey I would recommend the black headliner.
My own choice was solid black exterior, piano black wood (matches the exterior and extends the mirrors), beige next gen seats + premium interior + black alcantera headliner. At night with the revised more powerful dome lights, the interior is stunning. I have had many positive compliments from first-timers. Before I got the car I really didn't think it would create much of an impression. People love to rub the dashboard and the headliner..."wow suede, that looks expensive!"
