All good questions. Like you, my Marty shows the GT option, and does not mention the mirror; but I know that it was delivered with a remote controlled mirror on the driver's side. As far as the hole in the door goes, a while back we discussed the different number of door configurations (excluding glass). We missed the large mirror hole in the discussion. We did talk about interior differences: (1) standard, (2) standard with door speakers requiring holes for those, (3) interior decor without door speakers (my particular application), and (4) interior decor with door speakers. So if you take those four variants and add with or without the large mirror hole that would drive it up to eight. As an engineer myself, my tendancy would be to limit variations to reduce cost, and design all mirrors to cover the hole. However, if there was a handy dandy hydraulic punch that would knock it out it 15 seconds that would somewhat reduce the problem with all of the door variations (would not prevent mistakes, as you referred to in a previous post). As far as judging, I'm no where near qualified or experienced enough to give you direction. But that won't stop me...
From what I've read, though, assuming a concours class
, if you have either style correct mirror, with correct screws, all with good quality and workmanship, there probably won't be a problem. I don't think that the Marty report or build sheet or similar document is part of the judging process - my understanding is that the review is limited to the VIN, door tag, and possibly the body buck tag for those that have them. It would be good to hear from a judge though. With what you have reported thus far, I would go with the remote control mirror. Good luck. John
