Our cart looks something like this:
Now that's a pimp cart if I've ever seen one.
Seriously though, this cart has its advantages. It is very easy to transport the robot, and is also very easy to store, and cheap to ship, when it comes to competitions that are farther away or inaccessible by car. As much as we'd like to build one with a sound system, underglow, etc, there are still issues with transporting it and whatnot.
