No, I don't think so. $3000 on mass market cars, the average car sold now is $33,600, is only 8.9% profit before taxes and roughly 6% taxes. An OK return but not a great return. Probably better than GM and Ford get right now. Porsche makes a higher margin on lower volumes because it is somewhat exclusive much like Ferrari.
Hard to get investors excited about launching a new car company with all the risk with such a low return. It's OK for investors in old-line, established companies like Ford or GM but it won't generate the potential upside like a Tesla. That is the real barrier to launching a brand new car company that just makes mass market cars without some real market distinction.
