Sometimes you run across one of these dealers that has a 1987 Buick Regal T-Type, and because they never knew that the T-Type had many of the same features as a Grand National, they trump up their ad by saying things like, "1 of 1, a Regal built as a GN...." Same goes for a dealer that gets excited when they get a 71-72 Firebird Formula in the door, and not realizing the Formula could be ordered with the same options as a Trans Am, they believe it's a super rare car, one that slipped out the back door, because it has a 455HO.
