30K miles on it in 18 months- its broken in.
I've had about 5 or 6 Explorers- in fact still have an 04. When they went to the current IRS chassis I fell in love all over again. My first was 2WD and the best riding vehicle that I had ever owned. I had to trade it for a 4WD because of my work needs. That didn't ride as well but it is very sure-footed. I've towed a 3000# box trailer down a steep, snow covered road no problem. I gave it to my son and it will serve him well in college and beyond.
I didn't want an Expedition but my wife did. It's too big, ponderous, and barely fits in my garage. Now that I've owned it I really like it, again because of the ride- even better than the Explorer, plus the seats are incredibly comfortable and adjustable. My wife's driven it to Florida twice with her sports team- fully loaded up with 5 other people and gear, and she feels very safe and comfortable in it. Self adjusting air suspension, plus huge amounts of power and towing capabilities. Gear selection is 2WD, AWD, 4WD, and 4WD low, better than the Explorer. The traction control-ABS-anti roll system makes my winter drives white-knuckle free. I pulled huge logs around on my property like they were matchsticks.
