Alright so about the car im getting?

my dad settled on getting me a bmw x3 and people are infuriated cause i am 8 months over 16 years old...i know thats a car most adults cant get but seriously everyone i know has cars like those and i dont give a **** . i dont need the rude comments cause we are most likely picking it up in a week or so ..... why does everyone care i am getting such a nice car...i in 4 teens get into a serious accident in there first years if driving.. how much would you pay for the car then. so no rude comments but why is everyone so mad?
