Took delivery on 3/23/19 and was ready to fight for EVERYTHING I wanted 'fixed' but they did them already. Chip in the pano roof, GONE, all the CA HoV stickers, Gone, New tires on, and clean in and out. Fully charged at 100% since I was driving from NV to WA. Did I leave knowing everything I felt I should have? NO, they were delivering TM3's like mad and my Pre-owned TMS seemed to be a second thought. "here is a Model S, sit in it and get a feel for it while we finish your paper work, and we will answer any questions you have in a few" 40 minuets later, they were ready to sign on the dotted line. Out we were, like parents of new borns, strapped into our car's seats and off we went! Your preowned will come with 4 years 50,000 warranty and 8 year unlimited battery and motor warranty (from 2016 for batter and motor) so you will have time to solve any problems that might pop up. My 2016 TMS 90D has 52k (50k when I took delivery) so I have a little bit less time to have things to go wrong. Welcome to the family, enjoy the ride. My one advice it everyone knows how fast 0-60 Tesla are, most forget how fast 60-90 they are!
