Luxurious car. Great ride, quiet as a tomb and comfortable. Fit and finish is great, just don't roll down the rear windows at highway speeds. The noise and interior vibrations will beat you to death. The sound system and power door locking system is fantastic. The navigation system cannot be added to or changed while you are moving - very poor "feature". My wife has an Acura with a much better nav system.
The Levenson audio system is fantastic. The quiet, comfortable interior is well designed and good looking.
The navigation is all but useless, unless you want to pull off the road and program it. The system is only available by precise voice commands when you are moving. Good luck in you have a lisp, accent, stutter or there is wind noise or anyone else speaking while you shout your instructions.
