2008 Toyota Sienna LE 8-Passenger 4dr Minivan (3.5L 6cyl 5A)
I have compared all three major vans like odyssey, quest and sienna. No doubt Sienna tops among all three. With 8 passenger is really worth and the same thing in odyssey even kids can't sit it that middle seat (that much small). It's just a week I started driving this but still few negative points like you can't make the 2nd row as bench seat by removing the middle seat and no power option for opening trunk in LE models. If Toyota comes up with more option for LEs then no other minivan can come closer to this including odyssey.
Smooth ride, lots of space (wide), power sliding doors, etc
Backup sensor with camera option for LEs, easily removable 2nd row seats.
