I took driver's ed in junior high school at age 13. You were supposed to be 14 but they let me take it since I would turn 14 by the time the class was over. I got my license at age 14 and bought my first car for $50; A 1952 Chevy. I earned every dime of it and paid for my own gas, maintenance and insurance. That was a time when you could buy a 13-14 year old car for less than $100. It was also a time when a gallon of milk was 49 cents and gas was 20 cents. Minimum wage was 90 cents an hour and I remember working at Dairy Queen when the minimum was bumped to $1.10. For a high school kid, that was a lot of money back then. And it sure beat mowing and trimming lawns in the heat for $3-$5. And that was before weedwackers. Sidewalk trimming was done with loppers a few inches at a time.
In any case, times change. There's no way a high school or college kid could earn enough to buy a car now days and pay for the things needed for school. Even if you're looking at a 13-14 year old car. Those cars are pretty much junk or a money pit now with only a few exceptions. (My own!)

The old adage; "
they don't make 'em like they used to" lives on. Gone are the days of a tune up with a tach/dwell and timing light. And few kids today can even change their own oil. It takes parents to support the transportation needs of their kids. It's either that or your kids are selling drugs.
