Please no! I need the Model S style sunroof for headroom. If they do the X style windshield I most likely won't fit.
Okay, I'm missing something here.
I would have thought that the X style windshield creates more headroom than any other configuration will, unless your head is hitting/behind the windshield header at the B pillar.
Otherwise, the Model S style Sunroof is only taking the headroom back up to where the X windshield would be in the areas the sunroof covers.
