The old addage: “Buyer beware” comes into play here.
A bit of research goes a long ways, when buying high end, or any used vehicles.
There are multiple ways to verify a legit VIN, or expose a fake.
Often times, a deal too good to be true, confuses the issue.
My son bought an old non running truck about 5 years ago. The VIN plate was missing off of the door so i looked at the frame stamped one which didn’t match the title. We went to the PD and they ran the number but only in TX and the surrounding states. There is/was no national database for stolen vehicles. Unbelievable.
