I'm new to this forum, so please don't blast me for asking a question that has been discussed a fair amount. I am looking at purchasing a used 2016 Model S P100D from a 3rd party car dealership. When I called Tesla Customer Service the rep told be that he was just told that cars PURCHASED after Jan. 1, 2017 would not transfer the Unlimited Free Supercharging. I reminded him that this car was MANUFACTURED prior to Jan. 1, 2017. He said that his understanding was still that the supercharging would NOT transfer but he seemed unsure. Has anyone NOT had Unlimited Free Supercharging transfer on a private purchase of a 2016 model recently? I am nervous about buying and/or changing the registration on the car. It definitely supercharges at the moment. Any help or information would be greatly appreciated. Thank you in advance!
