I got my CPO in May this year. A couple of weeks after delivery I asked my delivery manager whether it would possible to get the repair/service history out of curiosity.
He said no problem, but it would take a while to get it from the headquarter.
After some time I received the detailled log in which they erased the previous owner's personal information.
I guess it's a matter whether your Tesla representative is willing to make the effort or not... ;-)
