The van is actually built by Ford, and although I have never associated true quality to Nissan, the product is more of a black eye to them, which probably explains their choice to cancel the joint project (Mercury Villager/Nissan Quest) with Ford Motor Co. The Quest was a great product in its first incarnation, but the second generation (this model) that started in '99 was ill prepared and obviously not given much attention, especially in the engine and transmission department. It has decent power, fairly good handling (at least the SE does), and offers decent room. The engine has held up quite well with nearly 190,000 miles on it, and the only major problem was a broken tranny oil pan.
One of the first vehicles with entertainment system, although it came with VCR, but it was back in '01. Has good handling for a minivan (the SE does), and it's shorter, narrower and lighter than the Odyssey, Sienna and others.
Nissan kinda knew this thing wasn't working, which is why they stopped allowing Ford to build it and finally put in all the stuff that the other had, including more power, torque, room, styling and features.
