You are correct - I just sold my Mr Norms Challeger TA in May of this year. Larry Weiner (Peformance West in CA) has all the original Mr. Norms GSD paperwork for all GSD cars . For a $50 fee he will check your VIN # and if there is a dealer jacket for the car, he will deduct the $50 fee from the price of the jacket. Dealer jacket will have the advance dealer shipping notice (similar to the monroney label), misc assorted paperwork, copy of the original order, any warranty paperwork (if it came back for service) and sometimes an original set of keys. It's invaluable to have this paperwork to prove provenance for a GSD car and if like me you did not have a buildsheet, it concrete verifies what options your car originally came with.
