 With only 30,000 miles on it, I've had 
too many problems.  One day all the 
electrical items went out.  We couldn't 
roll up the windows, move the seats or 
do anything electrical.  We could just 
drive the car.  Fron driver wheel 
squeeks when we turn.  On the positive 
side, it's interior is the roomiest on 
the market.  We looked at the Honda 
Odyssey, the Toyota Sienna and the 
Mazda van(Can't remember the name) and 
the Quest was much larger inside.  I've 
had no engine problems yet (knock on 
wood) and the abundance of extra's is 
nice.  Overall it's a good product, I 
just think we got a lemon as far as the 
electrical is concerned.
