 We researched all mini vans when we 
were ready to buy.  As like most of 
you, it probably came down to the 
Sienna and the Odessey.  We ruled out 
the Odessey in 2000 for the simple 
reason of not having leather seats. We 
would be bring how a newborn in our new 
car and the though of the first time 
she might get sick in the car with 
cloth seats was my decision only to get 
leather.  (The Odessy wasn't very 
stylish either.) We just replace the 
brakes at 30K and have never had a 
problem at all with our car.  We just 
saw pix of the 2004 coming in March and 
are thinking about the upgrade due to 
all of the new safety features.
