after all that I can't believe your still a fan of the Versa or Nissan in general. I would have jumped ship on the company all together if it were me.mine blew at 66k miles and 2transmissions (bad syncros in 3rd gear, but covered under warranty).
if you can get a 2.0, DO IT. :thumb2: totally worth it :ihih:
