Do they disconnect/unregister the previous owner when you buy the car second hand?
I bought a used Leaf two weeks ago from a dealer. From the dash computer, I saw the previous owner's CarWings username and password, as well as his address book, Bluetooth details, and lots of other history. I called Nissan to register the car with the Owner's portal (https://owners.nissanusa.com) and remember being surprised that I didn't have to give Nissan anything that proved I owned the car.
hmm, good point
Buy the "S" version if you don't care about the extras. It will not have the navigation module, so no carwings either.
