My experience over the last two years with the xpy has been great. I have had no problems with it. It is a well built, very comfortable highway cruiser. Average 16.5 mpg. I have the 4.6 L V8 and it has adequate power for my use. Super truck and would buy another without hesitation.
Room. Can drive all day and not be tired
Rear coat hooks (behind 2nd row seats). 3rd seat that folds into floor (understand this is coming in 2003). Outside of that, cannot really think of other changes.
