Yea according to the policy then:
How are used Tesla cars affected by this policy?
All used Tesla cars purchased on or before June 30, 2018 will continue to have the Premium Connectivity features described above at no cost for the lifetime of the car, and will be active for future owners if sold privately.
All used Tesla cars purchased on or after July 1, 2018 will receive Standard Connectivity and are eligible to upgrade to Premium Connectivity.
So i had no expectation that my used m3 would have free lifetime connectivity but it looks like they made the policy for used cars more generous after this. It was a nice surprise
