The 370Z is nearing the end of its run....Jay Leno showed the top designers what to build 3 years ago....gasoline is cheap now...why didn't Nissan have the new Z in the pipeline this whole time so they could deliver a new car as the 370Z drives off into the sunset....instead of a "concept" that is still 2 more years away from reality? Hate to say it, but Nissan ( or Renault ) doesn't know what to build next....they're fishing. They're throwing out a concept to see if people will bite instead of trusting what built the whole Z heritage to begin with.
