The movement of cars around the world requires a specialist type of ship and, while they may be functionally effective, they are not good looking ships.  They have the appearance of a box on the water.  The large rear loading ramp allows the cars to be loaded and then they get driven around the multitude of decks for storage.  This example was coming up the Solent and heading in to Southampton.  A similar example had a shift of load in this area and was put aground on the Brambles Bank to avoid sinking.  No issues in this case, of course.
