I often have elderly persons in this vehicle and they have all commented on the comfort of the leather seats and the spaciousness of the cabin. When it's empty & the seats are stowed there's plenty of room for hauling. I traded in an 8cyl Jeep which was seriously noisy; Sienna is quiet by comparison, but still loud on the freeway. I've had it just over 18 months and, knock wood, not a think has gone wrong. Mileage exactly as stated by the manufacturer (not to say it has great mileage but I am saying the advertised MPG is truthful).
The sonar is great - it's kept me out of two fender benders. Leather seats are comfortable & easy to clean, good turning radius, love the automatic side & rear doors. Row 3 seat removal is easy; just stow in the floor. Large trunk area when all seats are up. 6- trac CD player, automatic sunroof.
Would like a quieter cabin while driving freeways.
