We bought our Odyssey in August of 2000, about 6 months after we bought it the sliding doors started to jam and on several occasions would not open. To this day December 1 2004 they still occasionally jam but after bringing it to Honda in '01 it is a lot less frequent. That is the only problem I have had with this van. Other than that everything is excellent.
Folding rear-seats, spacious trunk, good gas mileage, excellent build (only a few scratches after getting into an accident) and good handling and traction.
Sliding doors, although after driving in a friend's re-designed for '05 Odyssey I see that problem has been greatly improved, as well as in the earlier EX models.
