I want to replace my 2015 S with free supercharging. And I don't want to lose stalks, gear selector, sonic sensors (the cheap easy stuff to add back). I don't have FSD, I have wondered if I could buy an old used Tesla with FSD and do a double move to a new S. My ultimate hope, they cut the price to 55k so it can get 7500 off, or maybe some tweak so the S counts as an SUV and thus has the 80k limit.
