A 3 year old Sienna or Odyssey is probably the best value in a mini-van today. Even though they're Toyota/Honda products, they depreciate pretty hard. A three old one has 80+% of its usable life left and typically costs less than 2/3 of a new one. A 2004 Sienna can easily be found for close to $20K flat, or less. Personally, I'd rather have a 2004 Toyota than the new Dodge.
That said, I know why people buy the new Dodge. Better financing rates, a full warranty, and so on. But for me, I don't really care that much about warranty coverage when buying a high quality product and even if you're financing, the difference is not so much that I wouldn't buy the Toyota.
