If you join the MCA then you can download the judging rules for the class you would be in from the MCA website. OK, obviously in thi case the 67/68 Shelby class. Hurry as time is short. Then honestly go over those rules and compare the what you see on the car. I'm not sure as a couple of years back they might have eliminated the Concours Driven class. That means everything is going to the higher Concours Trailered standard.
The judges in this class at MCA are also the same ones who judge at SAAC. Theres are no different folks. Just some newbies who hold the clipboard while the experts rattle off what they see (or imagine what they see).
