 legal adult and you do not need to be buying a girlfriend a car by the way i would tell you that if you're twenty seven except for the legal adult part i'll tell you not to buy your girlfriend a car because it's a good way for her to end up hating you or you hating her while you pay payments on the car it really does happen everyday we talk to people all the time on this if she wants to get a car i would suggest she work twenty four seven and your mom and dad coach her and feed her
