 Purchased used 2006 Azera Ltd. with 15,200 miles.  Tremendous car.  I miss the smoother ride of the XG350 I previously had, which was sacrificed in the Azera for better/sportier handling, however; I knew that when I purchased it.  Overall, I am very satisfied with the combination of handling, quiet ride (it's still very smooth) and performance/fuel efficiency from the 3.8 liter engine.  The interior features are all top notch with tons of space for comfort.  Six air bags and electronic stability control add some peace-of-mind safety features.
