That's a great deal, especially if they are selling you the car as a NEW CAR with the full new car warranty. That's a great find!
I personally would like to have a Model S with a panoramic sunroof that the Ravel suspension plus front motor. 90% of my driving is around town and I use the the sunroof quite extensively about 7 months of the year.
After getting used to the sunroof I find cars with a sealed glass roof to be almost cave-like
Also great you are getting unlimited SC. DO you know if the car has MCU 2.0 (the center display)?
