Correct me if I'm wrong , those who know X's better than me . Not every single GNX has or had the jacket and book . The orig owner got a thank you letter from Molly and it stating to send in your size for jacket and book along with your cars number ( so the book will be numbered with your cars number ) . As far as I know , not every owner chose to do so , therefore not every GNX had a jacket , or book for that matter . NTM , some owners that have sold their GNX , decided to keep the jacket and/or book . Again , therefore is why not every X out there for sale will have these items .
