"I looked at the definition of non-authentic, it has it's origin tied back to what the "Factory" delivered"

from the rule book: Champion Division is the most demanding JCNA Concours Division. It challenges its Entrants to research, prepare, and present the judged portions of their cars in their
original, authentic, factory-delivered configuration, and condition.

I am going to take that at face value, and ask, "Don't 'factory-delivered' cars these days always have plastic covering the upholstery, sometimes have protective plastic full or partial 'wraps' for shipping, etc?" Isn't the a portion of the ubiquitous "dealer prep fee" on an invoice the fee for taking a car from 'factory delivered condition' to ready-to-drive? (not to open the can of worms that those fees represent)

from iseecars.com: "A negotiable fee that is sometimes passed on to customers, which covers the dealership's cost of preparing the vehicle for sale. This can include removing plastic coverings, installing license plate brackets, setting the vehicle's computer, cleaning the vehicle, and adding fluids."

For owners of vintage Jags this may not be an issue, because I don't think these kinds of protections from the production floor were used, or even available back in the day, but if the literal 'factory version' of a car is to be the judging standard, how should that standard be interpreted in 20 or 30 years for the old cars of the future being produced now?

The general interpretation seems to be to judge based on 'new, showroom condition' more than the actual 'as delivered by the factory to a dealer condition.' How far off am I, and if not far off, shouldn't the rule and the interpretation be essentially identical?
