Grandpa walked to school in the snow. And we rode in the back of station wagons. What will our children remember? An available rear-seat DVD entertainment system with a 9-inch display, 115V power outlets and three-zone automatic climate control? Standard power sliding side windows, MP3-compatible auxiliary audio jack, and 14 cup and bottle holders? Kids have it so good that they might think that Sienna was built just for them. But with three-row side curtain airbags, side-impact door beams and 3-point seatbelts in all seating positions, it’s clear that the 2008 Toyota Sienna was built for the whole family.
