 I called myself trading up, from a 2001 Expedition to the 2006 EB model.  It was a big mistake, the interior of the 06 model is not as roomy as the older model. The gas mileage does not seems to be as good as the older model.  I liked the option to adjust the rear view mirror for night driving on the newer model you can not adjust the glare control.  I just am not happy with the newer model overall.
