While I have only owned this van 2 months, it has been in my family since new. It has had hardly any problems. I am very pleased with the leather interior. It has good take off power, but does struggle somewhat on long hills. Earlier models had gasket problems, but that problem was resolved for 2004. The headrest of the 2nd row captains chairs do create a blind spot when backing up, but I have learned to adjust to it. There are also a few rattles from the rear door when going over bumps.
Smooth car like ride. Good styling, nice leather interior. Great sound system, DVD system. Built in air pump.
The only improvements I can think of are more power for climbing hills, larger brakes, and the standard power door should be on the driver side.
