The Ford Expedition defined the full-size SUV as we know it today. It was the first to offer a ride and handling more akin to a car than a tank (of course, such a large vehicle cannot be expected to handle like a Miata). My Expedition has never given me a bit of trouble. It still drives and rides like the day I bought it. Unlike previous GM products I have owned, there are no interior rattles, and the only things I have ever replaced are the tires (65K), and the fluids and filters. It tows trailers like they're not even there, and it can't be stopped off road. I hope ever vehicle I own hereafter performs this well. Kudos to Ford.
Handling, interior comfort and ergonomics, vast amounts of space, and the reliability.
The 5.4L Triton is a good start, but needs about 35 more HP, and the fuel ecomomy is dismal.
