First of all let me start by saying that the Sienna and the Odyssey are the best minivans on the market today. They both are the most stylish and have the best quality. I looked at both minivans and what swayed me to choose the Sienna was the price. I just found that I could get the same quality, or better, in the Sienna and not pay as much. I do think that the Odyssey is a better looking minivan but the Sienna isn't far behind. I love the Sienna's interior features. It's very comfortable for everyone (average for those sitting in the third row). Nontheless, if you purchased the Sienna or the Odyssey you didn't go wrong!
Attractive dash display, good sound system, temp control for rear passengers, very comfortable ride, quiet on rode, quality controls
Vehicle exterior design could be better, second power sliding door would be nice but overall Toyota has done a good job with this minivan.
