We are really happy that we bought a used 2004 Sienna Limited edition vs Odyssey EXL. It has all the require elements that my wife and I were looking for in a minivan. Safety and entertainment features like side curtain airbag, DVD for the kids, parking sensor and handling. The mileage has not been bad. Getting around 16 city and 23 highway with full blast AC. The only draw back so far with the Sienna is that the tire doesn't last long. I am a conservative driver. Even with tire rate for 60K miles, I am getting around 27K. Oh well hopefully the Sienna doesn't breakdown on me until end of life on the new Michelin Hydroedge.
standard Side Curtain air bag for the current model, Parking sensor, and DVD to keep the kids quite during the long ride.
Better suspension so tire doesn't wear out to fast.
