But that doesn't mean the 370Z will never have a drop-top option available again in the future. A Nissan spokesperson told MotorAuthority that it will, emphasis mine, "not offer the Roadster variant for the current-generation Z beginning with the model year 2020." Thus, whenever Nissan decides to introduce another generation of its storied sports car, the Roadster has a chance to resume its place this mortal coil once more.

That's the $64,000 question. As MotorAuthority points out, nobody's quite sure what's going to happen with the Z in the future. Some reports have claimed that it's on the way out, but interviews with Nissan execs have found the car being referred to as a vital part of Nissan's brand, so it's really anybody's guess until Nissan decides to shine some light on the situation.
