 The Toyota is head and shoulders better than previous Venture and Caravan minivans.  It rides better and is much quieter.  The AWD works great and combined with the ABS and stability control it is nearly impossible to lose control or even spin a tire.  There is plenty of room for 7 passengers and the rear seats fold easily into the floor giving a flat cargo area.  While the Sienna comes in only one size, it is equal to the Grand or extended models from the competion.  The only negatives are the run flat tires that wear very fast & are very expensive and poor gas mileage (17 MPG average).
