This is the explanation from the original thread: So the way that they do things in Malaysia (can’t guarantee that’s what’s depicted here, but it a lot more likely)

Is that the original owner got the finance but could no longer afford the payments they unofficially sell the car. But not in a lump sum. The new owner just takes over the payments and sends the money to the previous owner so they can pay it off.

So, the original owner had the bank/finance loan. The new owner would take over paying the payments, but only the old owner makes the payments.

So the old owner stops paying, and the new owner gets screwed.
