Does anyone know if it's possible to rent a car at 18? I will be driving from Palm Springs, CA to Boston, MA this summer and was wondering if renting a car was at all possible at my age. I have found one or two companies based in California that rent cars to 18 year-olds, but do not allow the car to be driven out of state.. I will be driving with my Dad, who would of course be able to rent a car, but in which case I wouldn't be able to drive.

Does anyone have a solution?
