You should really look for a 06 3.0 . The 4.4's 4.6 4.8 all have major engine problems that will cost 6-8k to fix. Depending on the year and engine...timing chain guides fail to age not mileage. Valve steam seals , coolant intake plates or cooling pipes, valve cover gaskets, water pumps and on an on.

The 3.0 don't suffer from engine problems but the entire cooling system should be changed. Both models V8 or 6 all the front end parts wear out.

Around 04 05 the did some comedic changes and also have a better 4x4 system.
