At present, the new traffic law stipulates that novice drivers can't go to expressway within one year after obtaining their certificates. Besides, he doesn't even have a certificate now, so he feels proud to buy a car because he is learning to drive. This is a completely wrong concept, and loans need a lot of proof.
You can discuss with him, such as buying it every other year, or putting it on hold for a while. When he gets his driver's license out, he can find a car to practice his hand. In a few months, for the safety of himself and others, he will buy a new driver and a typical road killer.
