You can build your own golf cart by buying a 4x4 kit and then designing the frame around it. This will not be an easy project, but it can be done. Bold PVC pipe onto the floorboard to start shaping the frame. Install a pipe at each of the 4 corners. Connect the upper ends of the pipe to hold a canopy or cover. Install some seats and a holder for your golf clubs and there you have it - a crude but functional golf cart.
