I owned a 2004 expedition (Eddie Bauer).
I started having engine problems so very reluctantly I traded it in on a 2014 expedition. Now I wished I could've kept it. The materials used in the seats, the trim and the carpet is soooo cheap. My seats already have a worn pattern. The trim around 3 doors is coming off and my rear heat doesn't work. I am very disappointed. I absolutely loved my truck before and loved the way it drove. The 2014 drives well but as I said, "material matters".
If one needs a family hauler in comfort and roominess, this Expedition EL is still worth considering. Thought the V8 has been replaced by the more advance and peppy 6 cylinder with Eco-boost, the V8 is still more than capable than most folks will need it for. There's enough get go to haul a bunch of gear and people(up to 8) in the EL trim. The interior is a bit outdated but it still has all the bells and whistle one can use in a big hauler. The ride is composed and rather more secure than our other family hauler, the GMC Yukon XL. The seat is better and more supportive in the Expedition. We love both behemoths as they both get the job done for us. As far as roominess and floor layout, I'd have to give it to the Expedition. It has the best 3rd row seat roominess, leg room and seat comfort. Adults don't mind it as much sitting in the 3rd row compared to our Yukon XL. MPG for both is what to be expected in such large vehicles. Average 16mpg overall for both in city/hwy combined. If you can afford the fuel cost and cruise in style and comfort for the entire family, the Expedition is worth it. Beats having to travel in 2 cars(2 drivers), 2 car payment, insurance and over all travel risks in my opinion. Future option is to go for a mini van or a mid size crossover SUV once a couple of kids are in college. For now, we love our Expedition.
