I bought my GXE a few years ago with only 3 gears but this car was solid! i drove it all around GA and I even took it to Cape Coral, FL with no problems. I always wanted to swap the auto tranny but never had the funds for it but this Maxima can take punishment. I got rid of it after 300k miles i got it with 190k.
I mounted the sidewalk while driving 50 mph - no damage to camber, alignment, nothing.
I even went off roading with no problem either.
Whichever trim you get it is going to be reliable.
