Google search discovery-
MileOne- provides for all the automotive needs of its customers conveniently, on their own terms, through the largest automotive sales and service delivery network throughout 5 different states surrounding Baltimore. . . so basically a 1-stop-shop for car service? Not quite. MileOne is more of a client manager. They represent a network of cars and provide customers with every service they need from searching for a car to repairing it after a collision.

Our Mission:
To create an unparalleled car buying, ownership and service experience that puts the customer's needs first and results in a lifetime relationship with us. We will give our customers access to the car industry on their terms through empowered and well-trained employees who reinforce our mission every day.

MileOne allows you to search for the exact car you want and then will tell you where to go to buy it. They can do the same for locating parts and services for car maintenance.
From what I understand, there are no fees associated with using the website to find things. I am not sure exactly where the fees come in, but they have to charge for convenience. Whether the dealerships/clients are paying them on commission or the customer pays for information, the website must be profitable.
