I have 5 children, ages 8 to 20 eyars. I have purchased 2 cars for the older 2, but waited until they were past the 16 year old threshold. My wife and I wanted them to be sure they understood what was expected, and to prove themselves with our cars before buying them their own. Once purchased, however, the car became theirs: gas, oil, insurance is on their heads, not ours. They had a job in place before receiving the car. In addition, the cars were not too expensive, we paid cash for them; in the mid $1000 range. Anything beyond that is for them to purchase. Now, the next one is ready, but we are not. Only 16, no job lined up yet, so we, and he, will wait.
