Do they have a history of empty promises? Will there be possible obstacles in the parents" live in which they will not be able to afford to buy a car? Will they need to buy another car in the future for another sibling? Or maybe will the son need to share the car with another sibling in time? The answers to all these questions will be put into account Fortunately, an exchange between a child and parent is already to a good start because since the two transactors are family members they already know knowledge of the other's personality, family, history, church, and other relevant information to ensure that the exchange will be completed successfully. .
Transactions through relative could possibly be the most beneficial because there are lower trading risks. Trade agreements can be more personalized, and rules can be bent and re-agreed upon so that terms are advantageous to both parties. For example, lets pretend that the arrangements for a son to get a new car are for him to maintain a 3.0 GPA and get a job to pay for half the car. If the son decides that after getting a job, the time spent at work is taking away from school, making it difficult to study, the parents can decide to make a new arrangement. They do not want their son to get bad grades as a result of the arrangement; it defeats the purpose of its terms and conditions. Instead the parents and son can come to a mutual consensus to a new agreement that instead of paying for half the car the son can do chores around the home and get a 3.5 GPA. This agreement benefits both parties: The son gets better grades, can work at times more at his convenience, doesn't need to pay taxes to the government out of his paycheck, or pay for gas to get to work, the parents get a clean house, do not need to lend out their car for their son to get to work, and don't "need to hear any excuses why their child isn't getting better grades.
