Is there a good way to transport a golf cart with a 5er?

Rent one. I know the rates are high. But in the whole scheme of things, it is a lot cheaper in the long run. Avoid the initial purchase price. Avoid the cost to transport it. Avoid the maintenance. Avoid the hassle of loading and unloading. Something breaks...take it back. They won't let your kids, use it. But some think that is not a bad thing.
