Your teenager wants your old car, and suddenly that aging sedan has two very different price tags. A buyer might hand over cash for it, while your teen sees freedom, independence, and fewer requests for rides to school.
Keeping the car in the family can save money, but only if the vehicle makes financial sense for another driver. An older car might need expensive repairs, cost more to insure than expected, or lack safety features that matter for a teenager. Selling it could free up cash, yet replacing the transportation it provides might cost even more.
