Someone I know is selling a $60k classic vehicle, on Autotrader. A potential buyer reached out and said it was exactly what he is looking for and says he will etransfer $2500 per month to hold it until he can come to pick it up and pay the balance.
1st etransfer has been sent, seller is waiting for the bank to confirm the payment.

Seems sketchy, for both parties.
Buyer has not looked at the vehicle.

What is the potential scam?
Seller doesn’t seem concerned…
