If your customer has all the documentation to prove the vin is correct... such as the broadcast sheet etc. A reproduction vin tag can be purchased from http://www.datatags.com/. BUT.. he MUST have all the correct documentation. They won't touch it without proof.

On the surface it looks questionable at best. For a car that is in what appears to be excellent condition, its surprising to see someone Mig welded the vin tag. It is not uncommon to see them with Philips screws or rivets (usually used only as an insurance policy in case the tag's welds are suspect), but buggered up welds just don't make sense. If I were you, I'd be very skeptical. With a $99,000 price tag no one is going to fork over that kind of cash with a vin that obviously looks like it has been welded on by someone who failed a junior high welding class.
