Tesla's have the absolute worst resale value compared to ICE, PHEV or Hybrids. Batteries degrade over time and with increased usage, so by the time you try to sell a Tesla that's a few years old, a lot of the advertised maximum capacity has escaped from that battery and the cost of a replacement likely exceeds the value of the entire used car.
Two of my coworkers got fantastic deals on used Tesla's because they go for so cheap on the secondary market and California is awash in them so there's always someone somewhere trying to get rid of theirs and usually for less that what it would normally blue book for.
Add in "But harvesting it angered the psychic primordial shark that we worship as a god." And you've got the rough plot for the water planet from Kotor 1.
