You told someone else they didn't know how to value a company then went on to talk about gross margin and operating leverage like it matters at all to their valuation. Their manufacturing capability clearly is not why they are valued so highly. I set out a case why I think their car manufacturing is worth a fraction of their market cap (at best half the value of Toyota, VW, Daimler).

What was the Tesla the market cap when you bought at and how did you ascertain that was fair value or cheaper?

Also Porsche is part of Volkswagen - which has a market cap of $193B Euro. I seriously doubt the porsche segment is worth near the figures you stated and certainly not half the value of volkswagon which includes VW (duh) audi, bentley, lamborghini, Skoda etc. I don't think you have a clue.
