Only car I have owned since I moved to the USA.
It is great on saving gas money and it cam also take up to 7 people with the driver included. I like the comfort of it, it is very spacious and I love how it is wide rather than long.
2000 Nissan Quest: Great until it misfires
My family bought a used 2000 Nissan Quest in the winter of 2010. It had less than 70k miles on it at the time of purchase. For over three years, it served us without any serious problems. In the summer 2013, the distributor went out on the middle of the interstate at night. It was replaced with a Cardone Select Unit, after which the van operated without issue for a year. In 2014, the car failed emissions due to the knock sensor triggering the check engine light. We had the shop do spark plugs, PCV valve, and knock sensor replacement to get the emissions waiver in our state. Ever since that shop replaced those parts, the van had a random, intermittent misfire (ODII code P0300). I felt later on that the shop had done something wrong, but I made the mistake of not taking it back to them immediately. I thought it was a distributor issue, since it felt very similar to the first time the distributor died out on me. This time I installed a Rich Porter NS60. It did not improve the misfire at all, and I contacted Rich Porter, whose warranty covered me for a free replacement, which also did not fix the misfire/idle shimmy. The misfire was improved--but not cured---after a new Hitachi MAF sensor and front catalytic converter were installed. This one mechanic who I really trusted told me that he "could tell it was a vacuum leak, but I can't put my finger on where exactly". He said there was a very distinct sound in the idle that could only be produced by a vacuum leak. However my parents did not have the patience to keep the van and sold before we found out. Overall, it was a good van--but my advice to anyone looking at a 99-02 Quest or Villager (basically the same platform) is to be sure that you have a mechanic who can set the distributor timing to 15 degreees BTDC (before top dead center), to ensure your distributor has the longest life span. A lot of people are lazy and think that they can install the distributor without setting the timing BTDC because the vehicle must be lifted to set the timing. The 99-02 Villager/Quest had optical distributors which were not the best, but to be honest the OEM distributor lasted us 3 years without issue whereas the Cardone Select and Rich Porter distributors were not noticeably better (this contradicts the advice I got from the Villager Quest Owners group on Yahoo). It is not that easy to work on--there is a large black cowling which is blocked by a bunch of stuff. The cowling blocks most of the fuel rail and the rear three fuel injectors. So there is not much space in the engine bay to work on the car without removing a bunch of parts first. However in comparison to other cars I've experienced, you could definitely do far worse than a 99-02 Quest/Villager.
A reliable workhorse
It's a great van for family. Good engine performance - high torch at low RPM makes the van very responsive when you step on the gas pedal. Owned van for a long time and never had any mechanical issue. It still runs like a pony at high mileage. If you need a workhorse, this is it. If you are looking for a flashy one, look other way ;-). All the designs are very well-done for practical use. Some people mentioned the sticking gas pedal when start from stop. Be reminded that this is NOT the same issue as the Toyota gas pedal issue. This is not safty related. It's caused by a dirty air intake. I followed the instruction of cleanup and it went away. Overall very happy with the van and it is still working like a horse...
