Another vote for Honda Odyssey.

I was reluctant about getting a mini van. Drove a couple and didn't care for them. I drove the Odyssey and was hooked. I bought a new loaded up 2002 Odyssey that I loved, but when the updated model came out in 2005 I had to get it. I have the Odyssey Touring with Navigation and DVD and lots of add ons. It is a great vehicle. I love all the gadgets: voice commands, parking sensors, rear camera, XM radio, side sun shades, I could go on and on...I think of it as the mini van version of Kit the Knight Rider car! A lot of $ to tote around the kids and get groceries, but IMO worth every cent.
I read some info. about some new features Honda is coming out with on their cars (seems they will practically drive themselves). As soon as they are incorporated into the mini van, I won't be able to resist to trade up.
In our area the Odyssey is so popular, you often are parked with one on either side. One way I justified trading in the 2002 was because there were so many silver ones, like mine, that I couldn't find it in the parking lots!
Not sure how difficult finding a quality used one is. I know my trade was sold to someone in the service department before the salesman even closed the deal with me.
Good luck, have fun, welcome to the world of soccer moms!
