Don't do it!
Well, look. There are some people who are going to swear up and down that Consumer Reports is worthless and that they're biased and this and that. I think a fair look at their record would reveal that not to be true, as they have American vehicles ranked at the top in several categories.
Minivan is not one of them. Take a good, long look at the Chrysler Town and Country/Dodge Grand Caravan road test, and the reliability rankings. It is not a pretty picture.
There will always be individuals who will own a particular vehicle that is an outlier--somebody who has a car that is not known for reliability who swears that they've never had a problem with it, and vice versa. You really can't go by that.
In addition to CR, I would really encourage you to spend some time in that vehicle and its competition. Feel the plastics on the Chrysler, turn the switches, touch the leather, etc. Then do the same on the 2010 Odyssey, which is on its last legs--being replaced in a few weeks with a new model. But you'll feel the difference in quality and components. Look at the carpeting on the ground--in the Chrysler, its been thinner and less rich. Look at the headlights on the front--on the Chrysler, there's a much larger gap between the light itself and the shell where it fits, on the Honda, it is seamless. I could go on and on. There are a lot of little details. But in total, they add up. It isn't a close call. The same was long true for the Sienna, though I agree with CR's assessment that quality on the new 2011 Sienna has slipped a bit.
I've spent a lot of time in both cars...my dad owns a 2009 Town and Country Touring with the entertainment package. I own a 2007 Odyssey EX-L. My dad will be the first one to tell you that the Odyssey is the better vehicle, by far. Yes, his does have the old 3.8, which is woefully underpowered. The 4.0 is a better engine, but it is still much noiser and coarser than either the Honda 3.5 or the Toyota 3.5. Of the group, the Toyota's engine is the best, followed by the Honda's, in my view.
The entertainment system on the Chrysler vans is the best (pending what Honda does with the '11). I will give that it that much. That's about all I'll give it. The ride is rougher--more like a truck. The steering wheel itself is too large, and the steering itself is tougher to manage, with a larger turning radius.
I know some people simply want to buy an American car--I get that. However, between the Chrysler and the Honda, one of them is made in America, and it isn't the Chrysler. So these things tend to be a bit complicated.
Anyway, if you do buy the Chrysler, best of luck to you. My father's luck has been so-so--he's had a recurring problem with the sliding door, some plastic pieces have come loose, and his brakes were shot at 25k (and he ain't exactly Mario Andretti either--he more glides to a stop than brakes..but I digress.) My Odyssey hasn't been completely clean, either--we did need to have the transmission software reprogrammed. But that's been it, the OEM brakes and tires are still alive and kicking past 40k, and there have been no other issues.
Personally, I would comparison shop very carefully...lots of people still buy the Chrysler vans, so you won't be alone.
