It depends a lot on what age it is and what condition it is in. It also depends on how often you might use one with all six of you. I'm assuming yours is a 2 or 4 passenger electric. Gas carts are not supposed to be used at FW, but I see a lot of offenders there. I don't know if a gas would be of any real benefit over the electric, assuming the electric is tricked out with good components. Ours is stock, so we aren't speed demons, but it gets us around. We would like a six passenger, but we would then need a new trailer to move it, so right now we put three in the front and two in the back. Oops, now a new baby, so there goes 3 and 3. We've done it before using rachet straps to hold car seats on the rear platform. Not easy, but it works.
