Are there any car rental agenices in America that do classic 50's cars?

Question

Planning a road trip when i finish uni, i want to go from Florida Keys up the east coast to New York, then across inland to Chicago then all the way along Historic Route 66 to LA then from LA to San Francisco. I have found modern convertables to do it in, but i would love to do it in a big old 50's style car.

Thanks
