My Expedition is almost 6 years old with 71,000 miles. With just less than 36,000 the engine needed replacement. Last July 2005 with 67,000 it needed a transfer case. This past week in February 2006 the transfer case needed replacement with only 5,000 since July. At the same time Ford needed to replace the rear end. Quality is Not Job One. I would not recommend this vehicle.
