The Unsung Flagship Sedans Part 1

I like the idea of a flagship sedan.  One car that represents everything a brand is supposed to stand for.  A showcase for luxury, performance, comfort, technology and style or whatever else a brand wants to put out there to proclaim its superiority and dominance - with varying levels of success.

Some flagships are obvious pinnacles of automotive excellence and immediately come to mind - the BMW 7-Series, Mercedes S-Class and Lexus LS are just a few that come to mind.   Others are not.
