Thinking about buying an Oddessy

Hi-

We're thinking about buying an Odyssey early next year. One feature
that catches my attention is the valve limiting feature in the upper
line model (Turn off 2 valves when not needed). I'm also a little
trepidatious about things like this, as it hasn't had a lot of time to
prove itself as reliable and unproblematic. Has anyone had any trouble
with this? How is the durability of the Odyssey in general? I own an
Accord and had a Prelude before that, both cars are/were excellent and
the reason I'm going back for another.

Also, it doesn't seem like there's much reason to go for the touring
package over the top leather EX model. Run flat tires are nice, but
the rest of the add-ons seem unnecessary and not worth an extra 6-7 K.
Is there anything I'm missing here?

Thanks!
