The ARMY program is an example of doing it right. I don't know the numbers, I could guess, but what would be the point? I don't pretend to know the details on DSR's contract, but here are some thoughts. The ARMY sponsors the car (obviously) They also have a hospitality program. In most cases the hospitality is a separate contract. That's why some teams only do hospitality at certain races and not all of them. The ARMY also has a show car program as well as being involved in the Youth and Education program. I assume that Tony has a personal services contract that covers his speaking engagements and appearances on behalf of the army. And they have the Interactive Midway display. The cost of running the car is just one piece of the program.
