As probably the only person in the country that has had his 370z transmission replaced due to bad syncros, I can say that this sould NOT prevent you from buying the car. The real issue comes from blasting up the road through second or third and then shifting over to sixth. Don't do that if you are paranoid.

I don't believe skip shifting was really the problem. That was just a line from your dealer or Nissan and it doesn't make sense with how a transmission works. If anything, skip shifting, done properly, *saves* wear (which I assume is why you were doing it).

No, actually that is not how it works. The syncros were putting in a lot of overtime to keep up with matching the input shaft speed. They simply wore out from the abuse, which they were not designed to take. You can have the same issue in just about any car you do this in. While I'll admit it happened rather quickly on my Z, it was not completely unexpected nor unexplainable.

Hmmm, I posted in a similar thread about this and I have to say it again, skipping gears shouldn't have any adverse effects on your transmission. Maybe, MAYBE, the syncros but not the transmission itself. I have been skipping gears for over the last 9 years in cars from 5spd to 6spd and have never had any issues.
