Unfortunately it may take Sherlock Holmes to find the origins of the bogus VIN. The difficulty is compounded by the fact that you really can't search for actual VINs or sequences of VINs unless you're with law enforcement. The super easy thing to do would be to drive it & if it was ever to be impounded then c'est la vie. It would be very sad if it was someone's pride & joy that was stolen like the 'Cuda story.
