Yep.... my daughter got one of these offers on a car she was selling... The purchaser claimed to live in London and was going to wire enough to pay for the car plus shipping via his agent which my daugther was to pay when the agent came to pick up the car.
I told her to tell the buyer that to forget all the money transfers and wire the money to his agent and have the agent bring some $100 bills and they could go to the bank verify the bills and have the papers signed and notarized. She heard not another word.
This scam is on Snopes also.
It has happened here in Southern Indiana, also. An older lady fell for it and lost some money. This was a couple or three weeks ago. I agree with the one poster that if they want the car, they meet at your bank and bring cash. I would meet somewhere besides my home. I wouldn't them scoping out my house either.
