Well, it's not a Spec Racer Ford and it was not made by the SCCA, though they seem to share the same bodywork, and I guess there may still be other variants out there using this body too. I didn't know this when I posted the puzzle, and now I see how it can lead to confusion, but since the puzzle has made it to Pro level, I think the exact car should be identified for the point. So, still open. Remember, this car has been built by a company that also makes a Renault-powered version, but is not SCCA (the car has, however, participated in SCCA events). BTW, hats off to your sportsmanlike conduct.
