Can you get a Tesla serviced anywhere other than a Tesla dealership? Does anyone do this? Seems like it's going to be difficult to consistently sell $100k of Tesla parts for even 10% of their value.
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.
