Help! - Not sewing related

So, the time has come to think of a new car.  We're in a financial situation (finally!) to be able to consider heading back into the two car family world, and since our family has grown, we're thinking it is time to get ourselves one of these...

This one is the Honda Odyssey, which we have heard great things about.  Here is the reason I am blogging about this.  We haven't bought a new-to-us car in quite a few years, and so this is an unabashed request for advice.  If you happen to be a minivan owner, what do you have and what do you like/dislike about it?  Even if you aren't driving a big ole family mobile, what features are your must-haves, and what could you live without?
Thanks, and I now return you to your regularly scheduled sewing.  I should have some capris to show you soon!
