Looking at buying a Model S in Janunary. I am not having much luck with the CPO guy that runs the show in Florida. 4 times no contact. But, we will see how that pans out. Considering the P85 or the 85. I don't care about the performance side as already have really fast cars. (705hp and 500hp) But I do like nicell interiors. I know own P offers the Alcantara roof. but, I want all leather interior. Would this be the "nappa" option that's allowed on both models. How is the reliability of the 13/14 models? I don't care about autopilot. I also assume I can't add 4/50 warranty to a car if purchased used under 50k miles.
