An industry guy once told me the teardown firms were usually spot-on for off-the-shelf parts but often off by an order of magnitude on custom or in-house parts. Tesla has a lot of the latter. Also note the teardown guys tend to talk in terms of contribution margin, not GAAP gross margin.
That being said, I don't exactly why Model 3 costs so much. But it's not depreciation, labor or anything else in Tesla's direct control. They don't user super-premium materials. They have enough volume to get reasonable pricing on parts. All these things can get better, but they can't get that much better. Tesla has focused on stabilizing the production lines and getting costs down for nine months, with only minor improvements. The low hanging fruit is gone.
One clue is the number of employees per car. If you compare it to the large majors, I think Tesla has about twice as many employees per annual car production. I know labor isn't the largest component of a cars costs, but it is something. Also, does any car company actually have a positive net margin on its EVs? Or are they all cross-subsidizing? It could be that EVs just cost more across the board and will until battery costs come down another few thousand per unit. It can't be the metal, or other components (of which there are fewer).
