VIN # is issued when your order is accepted by the Order Bank. This is not necessarily when your order is sent to the plant for assembly. A low VIN # may remain in the Order Bank until the allocated dealership order is forwarded to the plant for production. The VIN # becomes a legal fingerprint for the life of the vehicle and contains build and option information.Curious - someone please explain any relevance between the vin # and the chassis # . Is one better than the other ??
