COGS- Cost of goods

Hello I have noticed very different COGS for each car in the various manufacturing plants. Can you please clarify.

Cost of goods for motorcorp is 41,261 for each car. Why is it so high?
Cost of goods for for Tesla Motors is 20,034 for each car.
Cost of goods sold for Supercars is 7,880 for each car.

The super cars looks normal. It is the unit price as shown in that plant’s page. The rest of the manufacturing plant pages show unit cost around 7840 but in the boardroom it shows such high costs for my cars.

Cost of Goods it determined by the location of the factory. Different countries have different costs.

In the portfolio table in the Boardroom, COG is showing your total spend for that manufacturer for the life of the business.
