I agree the N* is a robust motor, as it the 3.8 Buick motor. I've owned many examples of both, although the intake manifold gasket/Dexcool combo was a recipe for disaster ... mine went at the usual 60k. (LeSabre).
There are plenty of decent motors out their. The VQ engine in my 98 Maxima should go to 300k without any issues ... and the 4.0L in my LS400 is likely stronger. Change the t-belt, w-pump,and tensioners, and these
motors will often outlive the rest of the car.
I drive old cars, and experience has taught me that regular maintenance
is far more important than pedigree or country of origin.
