 Simply put, this car is not worth the 50+ grand.  At first glance, it has a nice appearance. Not as grand as its Navigator brother, but still impresive.  However, after having this car for some time, it becomes a pain.  When you're not trying to maneuver this huge car in traffic and parking garages, it's sitting comfortably in your local repair shop having its newest problem fixed.  Front door leaking air, power mirrors without power, loud road noise that become greater with time, occasionaly weird clunkling that confuses both us and the dealer.  Also, even though this car has a massive engine, its slow to accelerate. and its transmission is sloppy and gets confused shifting gears.
