At that age, I was a mom to a three year old, working full-time and going to school full-time. I took care of my own car. I understand most people don't have all that responsibility at that age, but I don't see how car maintenance is THAT big of a responsibility that they can't take care of the majority of the expenses themselves. If the parents help thats GREAT (I sure know that when my parents offer help, I TAKE IT!), but the parents shouldn't feel obligated.
