Newish BMWs have the same capabilities although I think a lot of it is disconnected unless you pay the subscription after 3yr. When I got mine certainly the old data had been cleared.
However I also recently bought a used Mini (62 plate) and it still had the previous owners phone book installed. Which I noticed when the car tried repeatedly to call 'Janet'. I don't know a Janet. That wasn't from a Mini dealer.
