I always wondered what thieves do with these vehicles though.
As the cars are stolen, its all easy money for everyone involved as the thief doesn't have to make 100k on it. Even a few grand could make it worth the effort. Then beyond the thief and the chop shop, no one needs know the parts are stolen.
In a way its a good sign for tesla, cars tend to be stolen at rates proportional to their popularity. It also means that there must be a functional market for the parts.
But, bear in mind, the difficulty in getting access to Tesla service or parts outside of the official methods is what makes the parts so valuable: There's almost none on the market to begin with. Those who need them (for whatever reason) will have to pay big to get them, since competition isn't driving down the prices. And most Tesla owners can obviously afford it.
