quick story and need an opinion

When the guy bought the car from you, it was up to him to verify everything about it, the same goes for the guy that bought the car from him. Any misrepresentations need to stop with the guy you sold it to. Sounds like his morals are kinda suspect, so I would definitely disassociate myself from him. If I met the new owner I would wait to see how he felt about the car and seller before I said anything about its history.
