The closest thing they offer is 3 years of free Supercharging on the new vehicle if you already have lifetime Supercharging. We just took advantage of that on an X that we're taking delivery of this week. They tend to only make this offer at the end of the quarter: December 2018, March 2019, etc.I have an early 2014 S85 with 70K miles and in tip top condition. Would LOVE to have a new one due to the AP features, but unwilling to give up the free charging. I have gone in to the local dealer (SF bay area) a few times to see if they would let me "transfer" the free charging to a new vehicle, but so far, they haven't gone for it.
BTW, no, we didn't give up free Supercharging to get the 3 years. We're not getting rid of the S yet!
