 We purchased this van for our expanding family in August 2006.  I think after two years I can provide good insight.  The van is comfortable and great on long trips, even with kids.  It will swallow anything.  The powertrain is smooth and powerful enough, if not all that responsive.  Fuel economy is probably what can be expected from a 4500 lb minivan, I get 16 mpg in the city.  The main problem is reliability.  I have had trouble mainly with the brakes, an O2 sensor, and I had a fuel pump go out.  I have warped two sets of front rotors in less than 25,000 miles, and Kia won't cover the second set under warranty even though they only lasted 10,000 miles.  Beware of this issue on this van.
