I did get the same email from the dealer I purchased my car, but next day I received an email from the manager saying there was a mistake. THat email was suppose to be for the Murano, but since my VIN# and email address was in their system I recieved that email automatically.
Then I received another email from a different dealer, but no confirmation if was an error or anything. Anyway I checked this official site and the 370Z is not even listed.
