I don't think this would have made him feel any better! LOL! So, you have an option for car and you want a moped?
Well, i can have a car when im 17 but ive heard you need to do like 24 lessons before you can pass. Lots of lessons = lots of $$$ Plus with a moped i can learn now and have freedom now! So yeah - but if i have a car i shall have one of these anyway..
try to wash dishes, cut the grass, clean your house... do all necessary things to persuade your parents... if nothing still happens be contented that your parents are still supporting you in your education. be grateful for everything. earning money is not easy you know.
