You say a Smart Car is too small for you? Shaq fits!

Smart cars are being seen more and more around the dragstrip used as pit cars. They load them on the back of the trailers-right behind the drag car. They are being preferred over golf carts because they are street legal and they can "run into town and back" and don't take up much more room. That's the best use for them..... that's being smart :)
They also make trailer hitches for them. My dad put one on his Smart car and bought a trailer from Harbor Freight, and he used it during hunting season to bring home deer, rather than spend money on fuel in his truck. Also, they do have a small tailgate!
