2006 Toyota Sienna XLE 7-Passenger 4dr Minivan (3.3L 6cyl 5A)
I spent considerable time comparing the Sienna with the Honda and Chrysler minivans. The Sienna has a better feel in handling and in comfort. There is plenty of power with the 233HP engine. The Toyota cost more than the other minivans but the drive and amenities were worth the extra. I haven't found any flaws in the vehicle yet, but I've only had it for 5 weeks. Draw backs to the Sienna are: low quality Turanza tires, a slightly higher cost in insurance than the other minivans, and gas mileage that does not live up to sticker expectations.
The navigation system is great (if you get one, make sure you don't look at it too much while you are driving), comfort in driving/handling is much more than I expect out of a minivan. Another great feature is 3 zone temperature control.
Make the back seat slightly wider. Use better quality tires (although they are quiet, they won't last long).
