Not a worry, Mercedes S-class and 7-series offer bullet-proof glass against Ak47.
A 2+ tons S-class with 75kg/m torque <5s powered AMG can destroy a truck if anyone gets really close to it. All mafe in Tokyo has one. I will not hesitate to own one if I were a multibillionaire.
I remember once, at the front door of a hotel in Jakata, I saw 4 G-class (previous model) line up (they all look identical) guarding a celebrity/official. Seems the G-class is pretty much a 'standard' for this purpose!
And, yes, no place is a safe place if you were rich.
