gnx's owners received the same boxed book but those books got numbered to match the GNX dash # and on the opening white pages included a introduction page for the new owner ,
the same book was released without the numbering or intro printing and in same box from Michigan , its a great 64 pg hardbound table book that goes into detail on the buick gnx and starts with buick racing history, printed on heavy stock with many glossy color pics and his pic makes it look small but its 9.5"x 10" and the cover is padded , truly a great collectible book
my guess this is one of the unnumbered books but if by chance it is numbered book the value is way up there and for 80 shipped would be the steal of the century
