This is a small bus that I created some time ago. The front seat has only on minifig, making it more of a hybrid between a bus and a truck. The back portion has some storage area, but really isn't suited for carrying people (unless they are laying down)
Front view. Note the rails on each side. This allows for maximum bullying of other vehicles when on a civilian road. The large lights provide for powerful illumination at night.
Behind. Again, bumber and powerful lights. Tint the windows to make border inspectors even angrier. No, the standard model does not come with air conditioning!
The side. A great many people expressed concerns about the fuel economy of such a vehicle. It's too bad the manufacturers didn't give a crap.
Interior shot with roof and windows taken away. The windows can be replaced with blocks to make the cargo a secret if the builder so chooses.
