The Explorer has faced some controvesy after a series of rollover crashes. The Firestone tires, along with faulty inflation instructions, were determined to be the blame by some.
The Explorer Sport is a 2 door model sold from 1991 until 2003. A Special Service Vehicle version was sold to fleets, particularly police departments.
There have been 4 generations of the Explorer. They were from 1991 until 1994, 1995 to 2001, 2002 to 2005, and 2006 to present. Some popular options and editions included the Eddie Bauer edition, the Limited edition, AWD, and Sport Trac. The Sport Trac mixed the usual SUV form with a small truck bed in the back. This new class is often called a SUT, or sport utility truck.
Due to liability concerns, U-Haul has forbid their outlets from renting trailers to customers who would be towing them with Ford Explorers from certain years. It is unclear if that policy is still in place.
You can find plenty of these sport utility vehicles on the used car market. Look for those rare gems with a clean history and low miles. The best place to look is EBay, where you can usually get a Carfax report that will detail a vehicles history. Cars and SUVs on eBay typically sell for 10 to 20% less than listings in classifieds.
