Honestly, I don't know much about cars and I'm pretty sure I wouldn't know it was a bullet-proof car if my Dad owned one. Besides, maybe he has his daughter chauffered in a different car. What has it got to do with the main theme of the story anyways?

Also, Fizz, I find it totally believable that the guy would beg for his life if he was dying. Most anyone would. Especially this guy--he's a taker, not a giver (except to his daughter). The moment of truth is when he is forced to admit he wouldn't do the same for Boda. And, hey, in the end, that admission saved his life.

Let's play a game: If the story were turned around and Boda was lying there dying, do you think he'd beg? I doubt it. I think the begging was very much in line with how the mob boss was characterized--he had worldly power, but was a weak person.
