So if you take the ASP in Q4 for model 3 at ~54k$, and margins at ~20% then cost to manufacture is 43k$ for the mixed options vehicle that this represents. I simply don't think you can start pulling off pieces of that sufficiently to get anywhere near profitable for a 35k$ to 37k$ vehicle and that's at the gross profit line. Let's say you want to get to 30k$ gross cost for the base model in order to sufficiently justify selling it, and that it covers op. ex and so on. Someone show me how you get from 43k$ to 30k$? The battery is less than 4k$ of that.
At the same time, the base model after incentives is now ~29k$ or a mid-range Honda Accord. That's entirely too inexpensive. They should sell too many of them. I think they are going to empty off the reservation list and jack the prices up.
Fixed costs vs variable cost. More volume means more profit per car. Process improvements mean more profit per car.
Tear downs of LR estimated $28k assembled cost.
Lower company expenses means less profit needed per car.
