Welcome to the Forums, Maynard! wow, 200K miles?
You should DEF contact Nissan USA before selling (if you have decided to sell it) you car. They may actually take the car and put it in the museum for having 200K miles.
The 370Z looks great and has all the new technology. World's first Synchro Rev Match,332 HP and a 30K price tag will move this car really fast out of the dealerships.
Hope to see you behind the steering wheel of a 370Z soon
