We purchased ours new and owned it for 10 years. I've never loved a vehicle more. It rode smoothly, handled like it was on rails, rain, snow or shine. It had a lot of room to haul stuff on trips to the beach loaded with entire family. Had plenty of room for my 6'7" son. Front seats were very comfortable, middle and rear seats were adequate. I drove it in 2 ft of snow without any issues whatsoever. In fact, this truck was a snowmobile! The long wheelbase makes it incredibly stable, and the AWD feature was just fine for anything I got into. I truly LOVED this truck. Sadly we lost her last weekend. My son was in an accident where he hit a telephone pole and rolled it. He walked away with only bumps and bruises! The fact that it's a large, solidly built truck saved his life. Mechanically, we had zero problems until just over 100K miles. It was time to change the plugs, and like others - we had 3 break off in the head. That cost $$$ to fix. Several of the catalytic converters went bad causing the check engine light to come on. Another expensive fix. We had to replace the coils after 100K miles too. We had the bubbling that others have mentioned in the paint along the leading edge of the hood and the tailgate. Frustrating because we kept it clean and waxed. The grey trim along the bottom of the truck faded but there's a liquid you can apply that makes it look brand new. The truck was gorgeous the whole time we owned it. I was so proud of it. The 5.4 engine had a ton of power and pulled our 21' boat with ease. I absolutely LOVED my Expedition and we are in the market for another one. Needless to say, I highly recommend it.
Just look up the slew of problems with the 5.4L in this 2006. Apparently it has a lot of issues that Ford decided to hide from the public and failed to fix. There is a class action lawsuit on the spark plugs. Apparently, there are lots of other issues, including cam phase sensors. Mine started idling rough, wife drove it a couple of miles home, 2 hours later it was at the shop. The shop is about 1 mile away. Got the call today. It needs a new engine!!!

2006 Ford Expedition XLS 4dr SUV 4WD (5.4L 8cyl 4A)
I've owned my '06 Expedition for 9 of its 10 living years. I purchased with 32K mi. now at 167k mi. (she runs smooth). Had the typical wear and tear repairs. I also am a very rough driver, and "Big Bertha" has kept up. The only major issue is the back lift gate paint that bubbles (doesn't rust due to it being aluminum). I've had it repainted, and will have to do it again, as I plan on keeping Bertha for at least another 4 years. This is a design flaw, and something any Expedition lover, like myself, needs to deal with to keep it looking fresh. There is plenty of room for the entire family and then some. I will definitely buy another Expedition when Bertha's time is up!
2006 Ford Expedition King Ranch 4dr SUV 4WD (5.4L 8cyl 4A)
Bought in July 15 with 83,500 miles. I've put 1250 miles on it. Nothing too bad to report. I figured with its age mpg would be a bit below the 14 city/18 highway mileage rating when new. City is right on. Highway it's doing a bit better, around 19.5 mpg. It's smoother and quieter on the highway than I thought it would be, even with the Firestone Destination AT's I put on to replace the Continental Contitrac TR's that it came with. All the electronics and bells and whistles work fine.
The only negative is that 2006 still suffers from paint bubbling on the front edge of the aluminum hood. I'm told this is from a bit of iron corrupting the metal and the paint pops. Doesn't really rust, the paint just bubbles. It may also happen on the lift gate. Not much to do about it but touch up here and there before taking in for a fix. I understand this may be common on early 2000's Expy's. As for me I can live with it. That's the only negative I found so far.
I'm expecting a few years of good service from the vehicle.
February 2016 Update. Things are still good after 5000 miles since purchase. City mileage has drifted down to around 13 mpg. Handled Mississippi river muddy bottom land just fine during duck season. Wonderful, safe, and comfortable on road trip to Green Bay from St. Louis for Packers game. No hydroplaning in the rain with the Firestone Destination AT's. Did notice that highway mpg is about 22 at 55 mph, 19.5 at 70 mph.
