I am figuring out how to make a theoretical new car factory and keeping in mind the costs and sales balance.

So far I need to know:

if the factory wants to use 1.2 billion to open, how would they borrow the money? ( usual interest, usual # year plan)

how much do the factories tend to pay in fees to build and run?

are there any yearly or ten year payments that the factories have to pay?

equipment /machines maintenance? how often? how often? any price ranges?

how much interest and for how many years do car dealers pay for floor plans? do they pay the interest to the company or to a bank?

and any other info you think I would like to know.
