My problem with these Nissans, and most Nissans actually, is that they're not very durable or have 'staying power'. What I mean by that is the interior fades quickly, the steering gets a bit sloppy, and the suspension loosens up more quickly than most other cars. A well taken care of Maxima with 100k on the clock feels downright beat up compared to other cars with similar mileage & state of repair.
As far as staying power goes, that comes down to looks. After a few years, Nissans tend to look quite dated both inside & out.
Of the cars in the same segment that IMO do not feel worn or look too old would be VW's Passat and the Mazda6. Those cars do have their own problems (mostly the VW) but I think they're better cars to live with and to drive. That's my take anyway...
