The word is that both Honda and Toyota do CVT quite a bit better than Nissan. I for one cannot say.
I have two Ford Focus and both are the normal 4 speed ATX before Ford went stupid to go to the DSP6 trans that has given them enough grief to match Nissan and CVT. My Versa is also the 4 speed ATX. All of those will run forever if you just change the fluid once in a while. Got over 200K miles on each Ford and 120 on the Versa and all run fine. Of course you don't get that last 10% mileage because they are not the latest design but at $5K to change trans ahead of time that mileage gain is largely something that does not exist when you put it next to a car that keeps on running forever, that is where true savings lie.
