Picked up my Model X Signature today in Springfield NJ. Quite happy with my choices. My DS told me the only thing they had to do was replace one sensor in one FW door. Problem with adhesive not curing correctly. Car is amazing to drive. Auto-steering is scary at first, especially when it is driving on a curve. The X perfectly maintained distance as traffic slowed and sped up on the highway. Haven't tried auto-lane change. One thing I found out that I haven't seen elsewhere is that all X's have the hardware for Ludicrous mode, but the $10,000 option is to activate it in firmware and change the badge on the back of the car. They actually had my car setup for Ludicrous but that was the one option I didn't select when ordering. So they hooked up a computer to the X and removed it. Honestly the X is pretty fast on Sport Mode. I haven't tried Insane yet because it was pouring rain today.
