Correct, the Versa NOTE is no longer being sold as a new car but, there should be plenty of decent used examples. And parts will never be an issue. The new RIO is very nice also especially if you can find a good used example of this most recent redesign. Reasonably powerful, solid, decent MPG, reliable, and if buying new, it has a great warranty!
I like the NOTE because it's larger and more accommodating on the inside than many, while still being subcompact on the outside. It parks & parallel parks easily. It rides better and is quieter than most in the segment, even on the hiwy. And it's not a total turd! You may have NISSAN's CVT tranny issues but, you may not! Not ever CVT that they made, explodes!
