Labels can be counterfeited as can just about everything else. I would bring someone with u who knows before spending any $$$$$ I have seen one or two that even had original GNX rims, Turbo, Turbo cover, suspension, dash etc.... and would be REALLY hard to distinguish from a real one. People change VIN#'s as well. The Vin# must match the car # Via GNX Registry. The Vin # itself will NOT tell u its a GNX so don't go by VIN # alone cause it could be a GN with a GNX Vin # from a smashed one and there were quite a few.
