Each family is different. Our daughter is 17 and her "work" is her school work, extracurriculars, and community service. We do not expect her to bring in money from a job outside of that other than the occasional babysitting she does when she is available. She is on my payroll (minimal $$ and it goes straight into her savings account) with our company for shadowing me a couple hours a week to learn the process of running a successful business, planning, forecasting, IRS reporting,etc.
I had a 2007 Mercedes CLK 350 in perfect condition, purchased and paid for... brand new for me. When we purchased this car, it was earmarked for her at 16. That is the car she got at 16 because it is a good, safe, reliable car still with less than 30,000 miles on it. We pay for gas and insurance.
She is very picky and protective of her car, LOVES it. Her first class at school is at 9am but she leaves by 7:15am to ensure she gets the particular parking spot she wants to keep this car in perfect condition, no door dings,etc.
Some kids can handle the responsibility and some can't. Our daughter is very responsible, driven and independent as well as a great student and Varsity cheer captain. Her goals are set above and beyond many students at this age.
Granted, she is not perfect as no one is and the only issue we had with her and the car was a speeding ticket. She was very upset, and it especially embarrassed and upset her because the law here is that you must go sit in front of a judge if you are under 17 and get a ticket. The officers know exactly when and where students come out of the lots and head home and they have speed traps. That is ok... I prefer her to now be very aware and learn from her mistake.
She drives a good 20 minutes each way to school at least one round trip a day. Most of the time there are 1-3 round trips with you count all the extra cheer practices, games, etc.
As for me, I was not as fortunate with supportive parents and I purchased my first car at 18 with money I made working 3 jobs through highschool not including the babysitting. I also paid my way through college and worked 2 jobs throughout college.
We will also be funding our daughter's college so that she will graduate debt free and get a good start in her career. We started saving for her college before she was born.
