I've upgraded from a 2001 Sienna XLE and boy are the improvements great! Quiet ride with better storage areas than my old version. The Sienna is now boxier which gives a much larger interior space. My kids love the power tilt chairs in the 3rd row. Can't get them to sit in the middle row very often. Liked the AWD, but didn't get it due to the lack of a spare and the run- flat tires are EXPENSIVE to replace and apparently wear out fairly fast.
Laser cruise control, power 3rd row seats, parking assist, LOVE the auto dimming mirrors and the navigation system is fun. Bluetooth! Rear hatch opener on key chain has proven very useful! The new folding 2nd row seats to reach 3rd row seats is fantastic when carpooling - or to get adults in rear.
There should be an option on the screen in front for driver (or passenger) control of the DVD/entertainment system. Hard to reach to assist those in back. Would be nice to have storage box for headphones/movies between 2nd row seats- to order is over 600! Fuel ecomony slipped slightly form 2001.
