They do....if you arrive together.
I've heard that some of the MCA officials were very upset with what happened at that show with respect to the SSP Mustangs in attendance, and what was publicly posted about it. I understand that an apology letter was written, so I hope that the issues were put to rest and we can move forward. Establishing a favorable "relationship" with the MCA is important.
With that said, I think we need to figure out how the cars need to be judged, which is exactly what I've been told is the concern of the MCA (much like what you posted).
Anyone can throw a lightbar, or dash/deck lights, on a car with some decals and show it as a "restored" car, but we probably need to assist with setting some sort of standard for them, depending on agency, restoration level, etc.
That's going to be a major project.
