Sounds like just anti union nonsense.
Union or not what is a fact is your dealer has its hooks into the cars with dealer add ons that they would not voluntarily give up the opportunity to sell. When I ordered, dealer pushed list added up to a couple of thousand. I don't recall if I'm left with any but did insist on no tinted windows, a dealer add on that my dealer considers a dealer default that everyone gets.
Also, you can be sure there is some desirable, maybe even necessary, prep/checking such as cleaning and liquids.
