 My first luxo-liner.  Executive jet indeed it is.  This is billiard table smooth on the highway.  Nothing like it around town.  Must haves are the panorama roof, and navigation and PDC (Parktronic).  I can live without 4matic and heated seats. Less complexity and weight.  People say "what is it?"  And it gets the same mileage as my '06 Honda CRV did.  Get one today!!  You'll never go back to the "others."
