Toyota's Sienna keeps getting better every year. The current version offers a strong V6 and 6-speed automatic transmission. Mileage estimates are up to 25 mpg on the highway, and the Sienna is the only minivan to offer all-wheel drive as an option as well as two seating configurations. Even the entry-level L trim includes such comfort options such as keyless entry, three-zone air conditioning and 10 cup holders. Toyota has also engineered a clever 16-inch LCD monitor that allows rear seat occupants to watch two different video programs simultaneously.
