Damn nice paint job.
My bus has little loops attached directly to the side of the bus--you hardly know they're there. Once you open the basement doors, though, you notice that the inside of the door has a similar loop, and a short stout rubber cord with two S-hooks, one of which is on the door loop, the other of which connects to the loop on the outside of the bus.
I'm not a fan of little plastic pieces myself, and my doors weigh a good piece, so I like the straps and hooks.
