My current Nissans are an Xterra and a PathfinderPretty sure the guy you responded to is basing his entire opinion of Nissan off of the Xterra, which along with the Frontier and maybe Cummins Titan are the only reliable Nissans.
I also have owned a Sentra SER SPEC V that as a younger man I flogged on the autocross every other week was at 145,000 miles when I crashed it, only thing that ever needed replacing outside of brakes/shocks, were the wheel bearings (lots of autoX), a G35 ( also a Nissan) when I sold it had 172,000 miles on it. Did not use a drop of oil and drove fantastic, soudned great.( I should have never sold it!). Only thing that ever broke on that was the window regulator, a radio button and the trunk release (all relatively low dollar repairs)
I could go on, but those are my high mile excamples from my drivnig history. My low mile trade ins will not sound impressive for being trouble free, since they were low mile.
PS: The 2k2 to 2k5 generation maxima has not been sold as new in nearly 20 years.
