I'm going to need you to explain exactly why you think an association of otherwise independent and competing dealerships is a "union".

They may be called associations in some states. I don't think you can open a certain brand dealership in a state with going through them.

Ford was trying to let customers order cars online and they would deliver it within a couple weeks or less to a Ford hub. Some states pushed them out before they could try it.

Because my anti-socialist upbringing taught me unions are bad. Therefor things I think are bad must be unions.
