What are the names of the actual car makers?
That is a broad question, they are a lot of them and not including the ones that makes dedicated vehicles like Oshkosh. I would suggest to go by countries and research from there. A lot of car companies borrow technology or build under license. So a lot of cars of one brand might have parts of their competitors. Or they borrow components within the same company. Like Toyota does with Lexsucks, they place Land Cruiser / Tacoma drivetrains and place it on their Land Cruiser model sugar coated with toys elevate the price by 20Gs and called the LX570. General Motors does the same crap with the Scalade and Lincoln with Ford Explorer.
