What scale? If Toyota sold 1 car per year they would need to charge hundreds of millions to pay for the engineering. Just making an engine to meet modern emissions will cost more than a billion, but since that engine will be made for a decade we can amortize it and say the cost of the engine is 100 million per car. However because they make many more than that their costs go down. Because they make many cars they have developed assembly lines - to build the whole factory is likely another billion dollars (I don't have real numbers), but if you are only building one car a skilled machinist could do that in a year for much less cost than a factory.

Thus my question - what scale are they targeting. At some level of sales their expected costs are right. However if demand is a lot more than they expect it could probably scale down to $10k, maybe less, while if it is less costs go up...
