Asking for a friend in distress. He recently sold his car with RWC certificate, even though there was an issue with the door but it passed the RWC test. Buyer came to his house, test drove the car and pay cash. It was a smooth transaction and my friend was so happy and went on to buy another car (newer model, more reliable).
2 week later the buyer came back, claiming there is something wrong with the door and the gearbox (the car never had a problem with gearbox before). They said my friend sold him a car with RWC but the car is not roadworthy itself, and that the RWC was a fake (lol). My friend offered the buyer $1000 to help fix the door but buyer did not accept, asking my friend to do the roadworthy check again, but this time at a genuine service centre (i.e. go to Honda if the car is a Honda). My friend refused to do so, as the name transfer was completed.
Now the buyer threaten to report my friend to the police, and sue him because of the 'fake' rwc. My friend is so worried although I don't think he did anything wrong. A licensed mechanics did the rwc for him and he still got the receipt.
If you were the buyer, what would you report/sue my friend for? In my opinion, it was the buyer bad luck which my friend was willing to assist with the $1000 offer.
Update: thanks everyone for chipping in your opinion. The buyer has calmed down and asked nicely for a share of the gearbox repair, no more threats to sue or report. My friend is considering it, but this time under no stress. It's now totally up to him. He would like to thank everyone comment here, reading them made he feel much better.
Update: he's been recording every phone call from the buyer, just in case he threatened the safety of my friend's family. But there's none.
Final update: thank you very much everyone for chipping in your advices/opinions. My friend got a big relief reading these comments. They really helped. In the end, he decided to help the buyer $1000 fixing the gearbox. Both my friend and the buyer came from overseas (same country) plus the buyer bought the vehicle (a van) to start a business. I think that's the reason why my friend want to share the bad luck with the buyer. And I respect his decision.
Stopped reading at 2 week later.
Nope. Buyer beware. Too bad.
It's just a scare tactic, ignore buyer and move on with life. Nothing they can do at all.
