My biggest problem with this story is the details are so vaige..In this time of camera phones and the internet, you mean to tell me that no one got a picture of this car ? No buick enthusiast knew of this GNX's whereabouts in the first place ? No one wanted the notoriety of breaking this story with more details, car dealership name, GNX number, and a picture ?
My bet is this is a black turbo regal with a GNX badge on it....
