The Sedona is an affordable, well-built and reliable van.  It handles very well and has a surprising amount of power.  The 3.5L V6 can sound downright sporty under hard acceleration.  

The Sedona is very comfortable for long trips and quite versatile.  The standard 6 speaker AM/FM/CD sounds really good, and most controls are logically placed and easy to use.  The fit and finish is quite good, trailing Honda and Toyota by only a model year or two.  Some plastics feel and look cheap, but all are durable.  The cloth used on the seats and door panels is very nice quality, and the highly-adjustable driver's seat is appreciated.

While the Sedona may not stop traffic, it is a nice looking van and, because it's not as big a seller as Caravans and Siennas, it has a little bit of a quirky side.

Lastly, the Sedona gets top safety and reliability marks, so that's always comforting.

I like what I've read. Sometimes I've read negative reviews. It's mostly about the Sedona brakes. I gather that the weight of this vehicle is the cause of the brakes having a short life span.
