As others have said. Not cheap. However, I feel like being able to drive stick is an important skill, so I would encourage you to at least visit this skill in their driver training. It will allow them to drive any car in an emergency, and they may be able to get a great deal on a used car because all the other saps in the world don’t drive stick. I dunno my father taught my 2 sisters and i on a stick shift and now all three of us own stick shift cars.
