The Honda Odyssey and Toyota Sienna go back and forth every couple years as the "best minivan." Things likes handling, reliability, safety, MPG, etc.
We had a Plymouth Grand Voyager (aka Chrysler Town and Country, Dodge Grand Caravan). It was okay, but it fell apart too quickly, IMO. I would probably steer clear of Chrysler branded minivans. The one great thing about the T & C is the Stow and Go seating.
