Good price. I just bought mine for $38k. Almost exact same vehicle. Differences are, yours has rear heated seats and premium sounds, mine has nappa leather, dark bamboo, and 20" wheels. Mine had 40k miles and CPO.
Never drove a 4.4, however, I love mine. Good power and great handling. Looks better too, IMO.
If you like it, get it. The CPO will help ease any big issues. Do you have any factory warranty left? Mine is good until July, so I am getting every little thing I can find, taken care of.
They are replacing the rear door shadowline trim, due to a peeling spot, and the right side roof rack, as there is some bubbling under the paint in one spot.
Plus I am getting the brake fluid changed as it is due, and still under free maintenance.
