Well, back to your initial question, I think I listened to the same thing you were watching about the Model 3 being a cash generator...
My take was that, up til the Model 3, Tesla couldn't get terms from their suppliers. This is easy to understand when you look at the history of startup car companies. When they wanted to build a batch of cars, they'd have to go through a sequence something like:
Order parts - pay for parts - receive parts - build car - deliver car - get paid
<Next Batch>--------------------Order parts - pay for parts - receive parts - build car - deliver car - get paid
<Next Batch>--------------------------------------------------------Order parts - pay for parts - receive parts - build car - deliver car - get paid
In this example, they'd have to pay for three batches of parts before they got paid for the first car. As production ramped up, the amount of money they had to have on hand to pay suppliers would ramp up also.
What Elon said was that suppliers were eager to get designed into the Model 3, so eager that they were willing to sign up to (IIRC) 60 day terms - meaning that the suppliers wouldn't require payment until 60 days after delivering parts. That means that the production process for the Model 3 could be:
Order parts - receive parts - build car - deliver car - get paid - hold on to money - pay supplier 60 days after receiving parts.
<Next Batch> Order parts - receive parts - build car - deliver car - get paid - hold on to money - pay supplier 60 days after receiving parts.
<Next Batch> ----------------- Order parts - receive parts - build car - deliver car - get paid - hold on to money - pay supplier 60 days after receiving parts.
You can see that, assuming it takes less than 60 days to build and deliver a car, you could be sitting on a pretty good pile of money (from Customers) before you have to pay your suppliers, and that this continues as you ramp up to high production - you collect money from customer at the higher production rate before you have to pay for the ramp up.
