I was just looking back through the various reviews when I noticed one I wrote in August 2002. Three years later, I still own the same Maxima which now has 150,000 miles on it. The car rides like the first day I got it and basically requires little other than basic maintenance. The vehicle has aged very well and I still highly satisfied with this purchase.
Power, fuel efficiency and Bose sound system
none that I can think of although I'm sure the new models have improved upon a number of things.
