Hybrid Car verses Any Old Car

I was thinking about the hybrids and how much energy they save with regard to natural resources and then I started wondering about buying used cars and how much energy they save with regard to "recycling".

No energy is used to make another new car.

Will the hybrid save as much energy as the used or recycled car? One saves natural resources by using less of them and the other one also saves natural resources by using less of them. But, which one saves the most energy in the long term? Because it's the long term that determines what needs to be done now to help save our Green Earth.
