How can you start a car company?

First you need money. You also need to have a lot where you can sell your cars on. You want to have a lot where in a city or town not in the middle of no where. Then you obviously need cars to sell. You can buy brand new cars or you can buy used and then sell them. As you sell cars you will have to get more cars to continue selling. It's harder than it sounds but it's very do able.
