There are other stable points in the Solar System, that require only enough fuel as it takes to get there, and that is asteroids. You land on one, no more fuel needed. Just find one or two in the right orbit and a good resonance with Earth and Mars, and you have a free ride. The only hard part is that asteroids tend to tumble through space, changing their orientation constantly. Tethers could be used to slow that rotation, making a consistant orientation.
