I know I've seen discussions about this in the past but can't seem to find them now. I just sold my 2012 MS and need to prepare it for the new owner tomorrow. Should I do a factory reset, and if so, how. Would prefer that historical navigation stuff be wiped, homelink entries eliminated, eliminate driver profiles, etc. Any downside to doing a factory reset? Also, I assume I should contact Tesla Service to let them know the car now has a new owner. Any official way of handling? Thanks.
