This Explorer is extra clean and priced very well. It runs and drives just like it looks. The interior is very nice except for a wear place on the center console where you rest your arm.The tires are good and the all wheel drive is great. If you don't need it, fine. But if you do, there is nothing to do. It will engage as needed. It is perfect for your wife because she will get around fine, rain, snow, or sunshine!
