I am selling my early 2016 Model S. I am the original owner and took delivery in December, 2015. My spec sheet shows "free unlimited supercharging" and under subscriptions it shows "premium connectivity - free unlimited". My understanding is that as long as the car is sold privately, these features will transfer with the car. However, if I trade it into Tesla, or perhaps even another car dealer, all bets are off. I get that - I must sell it privately to have the "free" features transferred. I also realize that beginning sometime in early 2017, Tesla's policy regarding these features and transferability changed, and then changed, and changed, and changed again. These changes only applied to cars sold from those points forward, as they could not make them effective retroactively.
So I will be selling my car with a couple of valuable features - free supercharging and free premium connectivity, and of course I want to advertise this. My problem is that I cannot find anything in writing from Tesla that states this. The Tesla employees that I have spoken to understand my situation and agree with me regarding the transferability, but cannot send me anything in writing. One said that he found a document confirming the above, but could not send me a copy as it was an internal use document only. Others who are just too new with the company, or have had their brains scrambled over the years with the constant changes, have flatly stated that supercharging is not transferable.
Does anyone have a Tesla document or documents referring to this? Or can anyone refer me to where I can find them? My fear is that if I advertise the free features, sell the car, and Tesla for whatever reason discontinues the "free" aspect, I would at the least be deemed a liar and at the worst be open to a lawsuit. I have read comments on this forum from people who have seen it go both ways.
