The Sienna LE is an outstanding vehicle for any size family. I love all the room, it handles very nicely and goes from slow to fast quickly. It is not sluggish, which you might expect from a minivan. This vehicle is considered a luxury vehicle to our family.
Cons: The sloping front makes it difficult to determine where your front end is, I bumped into curbs a lot; still, that could just be me, I loved the Sienna.
