I need to make an excel sheet of all the different financial costs and benefits that any project can have. I am choosing to focus on any car manufacturer, I am looking to factor in all the monthly, one-time payment, and end of life salvage values that will be taken into account. like: land to start on, employees' monthly salary, monthly materials, any end cycles after 10 years. etc.

please list all you can think of. and detailed. also, note what might be problematic and could possibly be improved to create better benefits, thank you.
