Teenagers / Classic Cars ??

I'd go with something much newer.

Kids are irresponsible in cars, and the consequences of irresponsibility are much lower in newer cars.

FWD, 4 cylinder, airbags. New cars sacrifice themselves to save the occupants. Old cars, your kid is the only compressible component onboard.

People were driving these old cars back in the day in my high school, and there were a lot of casualties. And there were a lot fewer cars on the road. And there were no cell phones.

If you want to teach them about maintenance, you can do that on a new car too.
