  5. For Sale: 94 Geo Metro EV project - $3500 obo

    It solar-charges and drives but it still needs work and I'm out of time: -Headlights, brake lights, and turn signals are not hooked up yet -Something about my design is flawed; either the motor, the controller, or the battery pack is underpowered so it only drives on flat ground.
