So I may be the voice of dissention here....
I used to drive a Lexus RX 300. As soon as we bought the big Britax seat (still rear-facing) we realized that our Lexus was not going to work. So we bought a brand new ('04?) Odyssey with the high-end everything including the GPS. Well, perhaps I was spoiled with the Lexus, but I hated the Odyssey.
It drove fantastic, but it had a bunch of stupid features that were not well thought-out. The GPS was horrible compared to the Lexus, and in the end, I sorely wish I had bought a Sienna - just because it had a layout and feel very similar to the Lexus.
Anyway, we went through a financial reorg (ala Dave Ramsey) this year and sold the Odyssey. I do agree -they hold their value very well, and we were very pleased at what we got for it. We bought a very old Chrysler T&C. ('97) It worked great, drove great, and I was actually much happier in it because I knew we didn't pay a fortune for it. Mileage was awful though. In the end, I decided I just really needed those power doors. I drove the Chrysler for close to a year, and we sold it for a little more than we bought it for!
So I asked DH to sell the Chrysler and find me a decent van with power doors and a DVD player in it. So he found me a Dodge Caravan that met my criteria, and I really like driving it! Again, it didn't cost a fortune and has more features than our old Odyssey (DVD, power rear hatch, triple zone auto climate control, to name a few). I have no idea how it will do in the "repairs" arena. We've had it for a couple of months.
So I would suggest that if you want to pay cash for a van, stick to Chrysler or Dodge. You'll get lots of features for the money and have a comfy ride.
