Be careful, later get haul up for questioning.
Not say that don't give others a 2nd chance. But in many of such loaning of personal cars, sometimes its very hard for owners to find back the cars and even when they found it and wants to take back the money owed, they are in no man's land because in the 1st place, they are not allowed to have any private settlement on loaning of private cars.
I have a friend who loaned his car to someone else because he cannot keep up with instalments. After 4 months, the person who loaned his car could not be found as he has already started defaulting on payment. When finally caught up, his car was found parked at another condo.
When confront the person for payment, he say he got no money. You cannot report him, because private arrangement is illegal. You also cannot report that your car is stolen, because if the story comes to light, its a false report. All these is based on trust, but sometimes, friends of 10-20years also can betray each other for money. Some things are best not to be loaned so that 人情留一线,日后好相见。:p
