I'm buying a used Model S and I have the built sheet from the owner. I have a few questions about the options. Is this essentially fully optioned out? Also, I see that he paid for the performance seats. I thought these were 2014 seats, but this is a 2015 vehicle? So will they be gen 1 or gen 2 seats? The car was ordered on March 30th, will this car still be on 3G or LTE?
