We plan to run some enduro's with co-driver's next year. I have two driver's in mind that I trust in the car. And by trust I mean that they are very accomplished driver's and could pay for the car if they wadded it up. Anyway, I just wondered what kind of deal everyone else is doing as far as sharing expenses. Do you charge a flat fee, calculate the costs of the weekend and split it up, etc... I've been asked to provide a price and I'm not sure what would be fair to charge for an ECR race in an ITS car on Hoosiers.

Thanks for any suggestions.
