My parents bought my first car for me when I was 16, and then also bought my 2nd one for me for my 18th birthday, and possibly will buy one for my 21st. (I don't have a job so there's no chance of me buying my own haha)
When I had my car, my parents were helping me make the payments. I paid about 200$ a month and them 100$. I didn't bring it to college though so they sold it.
