 My 2000 Pathfinder is now 4 years old 
and going strong.  I only have 33,000 
miles on it, but use it daily and 
haven't had any problems.   Quality is 
excellent.
 Like others, my only complaint is the 
lack of power and fuel economy.  
Before this model I had a 1997 
Pathfinder and it was underpowered as 
well, but perhaps even more so.
 Although I'm not in the market for a 
new car (I loathe the thought of 
spending $30k for a car) I'd buy 
another Pathfinder in a minute.
