You start off with 510 coins. There are three factories ( Engine, Wheels and Car body ) Each factory is 170 coins. Once you have bought all three factories you can click on them. Clicking the engine factory will give you one engine, clicking the wheels factory will give you four wheels and clicking the car body factory will give you one car body. Once you have one engine, four wheels and a car body, you can make one car. Once you have one car you can try to sell it. The higher the price, the less chance you can sell it. Once you have 500 coins you can buy a new upgrade ( There is no point of buying at the start because the upgrade is related to the three factories. Keep following this process until you have one-thousand-and-five-hundred coins. At this point you can invest in Ferrari and earn two-hundred-and-five-hundred every five seconds.
