 My wife and I did a lot of research before buying this minivan.  We narrowed it down to the Toyota Sienna and the Mazda MPV.  The size of the vehicle was the primary concern because we have a small two car garage attached to our Cape style house.  I drove both the Sienna and the MPV into the garage when test-driving.  The MPV is smaller, and therefore was a more comfortable fit.  When we test drove both vehicles, the Sienna had a smoother ride, but the braking was more laborious.  The MPV felt more sporty, and the braking was much easier.  The Sienna had slightly better gas mileage (1 mpg better).  However, the MPV just had so many more features for less money - and all of that with a government 5 star crash rating.
