Silver Cloud invites two distant cousins to come together in the Rolls and the Metro. The Metro it turns out is far more important for the survival of the Rolls and swallows it whole several times over. The Rolls doesn't look out of place in the Metro and actually gives a nice harmony to what's being seen - two things beautiful in their own right and created by people but far more beautiful with an absence of people. Without the occupants of the Rolls or the Metro there is no class, no judgement, no status.
