I would check out the new Ford Edge. I had a 2.0L Titanium AWD as a rental recently. Extremely comfy, even though it's a Ford it might as well have been a Lincoln for its luxury. This was the quietest car I have ever been in by a huge margin. It is almost totally silent, you can barely hear any external noise at all. 2.0L turbo had great pickup and torque considering it's a 4400 lb CUV. If I were to buy one I'd get the 2.7L Sport version which is supposed to be amazing (0-60 in 5.5 s!).
