help with vin #

well I hope the tag matches the title. This was a Georgia car for the longest time. little old man owned it. he died and then the car was passed to his son. he died. This was in Georgia. Then somehow a man in Michigan found this car who was a mechanic and he bought the car for his girlfriend who had learned to first drive in one of these cars so he bought I for her. He went through the car and did several thousand dollars worth of work on the car and she left him. He had spent $600.00 to have the car brought up from Ga. he sold the car to the owner now and this guy bought the car for his wife and it was titled to him back in June of 2014. They just had a baby 6 days ago and plans changed so he is selling it now. If that title doesn't match the vin tag, how did Michigan accept the car out of state when they checked it and issued a Michigan title on it. Ifit doesn't match, someone down the line screwed up. How does one go about getting it fixed. Does he do it in Michigan, or do I have the title transferred and have the title researched in Ky and have it fixed. I know the title and vin tag will be checked by the Sheriff's office in Ky. here before they will issue a title in Ky. I have never ran into this before. has anyone else. Thanks,Bill
