When you want to make money selling cars you have to know the value of cars. Any car will sell for some price. That price can be your profit. Jose doesn’t speak much English, which makes it tough on him to communicate with many people. Despite the language barrier, he made a profit of over $30,000 last year selling used cars from his front yard. And he did this without knowing how to get a dealers license. Although he is a mechanic, and that helps, but it isn’t the key to his success. When you can look at a car and guess how much it will sell for, the rest is easy. You’ll eventually buy a car, and sell it for a profit. Then you can and repeat the process.
