Wow, yes sir, what a darn lovely caring thought and I would think that if your heart says it is the right thing to do but your brain has some doubt, I say follow the heart. I like the idea of sitting the young man down and discussing the maintenance and general care of the car so that he appreciates that cars do need the loving attention we proudly give our vehicles so that he realizes that with the gift comes responsiblities. Make it known that you are always open for any queries to help him enjoy a long excellent relationship with the car resulting in him enjoy the privilege of automobile ownership.
