How do you persuade your parent to buy you a car?

be responsible

show them that you are mature

tell them it is embarrassing

tell them what if there is an emergency

get good grades

be polite

be respectful

be peaceful

be calm

do not talk back

ask politely

help around to convince

Or do what I did, move far away for college, pay at least half your tuition, let them come and visit you and see your need for a vehicle, when they see you working hard and struggling, they may buy you a car.
