the info here is quite erroneous. I have personal experience with multiple P100D's... from 2016 and Jan 2017.
Free unlimited supercharging and FSD will only be removed if Tesla has ever taken ownership of the car. If there have been private party sales that ultimately resulted in it ending up on a dealer lot, these will definitely transfer.
On the other hand, if this dealer took possession of that vehicle bc it was traded in to Tesla or was a lease return, and Tesla auctioned it off (as they would do for an older car), then Tesla will definitely remove FUSC and FSD. Take a look at the ownership record on a carfax and decide. I have had a P100DL that was auctioned from carmax to another dealer, and the features remained... Tesla cannot just remove features due to ownership transfer unless explicitly stated (SC05 / 'non-transferrable unlimted supercharging' is an example)
If you can show the rest of the screen from that screenshot, one can tell if it has MCU1 vs MCU2. This X should have AP2... you can upgrade to AP3 with new cameras and FSD if you like (for free if FSD is purchased already).
it definitely has ludicrous
looks like it has the 22' inch wheels?... 100% will probably now be around 250 miles and real life experience at 75 mi/hr is going to be around 175-190 (bc of those wheels)
