I think the model 3 is going to kick butt, especially low to mid range Beemers and Mercedes. As Motor Trend reviewer implied, all of those feel like wet sponges in comparison. The S and X have basically killed the higher end market for the Germans where I live. However, Musk acknowledge that building cars at volume is 100X more difficult than prototyping and imo probably 10X more than low volume production so the uncertainty needs to be discounted. Not sure what that discount ought to be currently although I am guessing there is too much optimism in the stock. The shorts have no thesis if the latest short article in seeking alpha is representative of the quality of the short thesis. Option market prices two standard deviation risk at +/- $100 in Jan 2018 when we should get a pretty good reading on how well manufacturing S curve is being climbed and whether there are any significant recall issues.
