Yes I agree Gary, there is definitely a fear when creating these sorts of classes to go too far in either direction, rather than achieving a happy medium. While expecting cars to be 100% as they were in a specific year is taking things too far, on the other hand I wouldn't want to see a car that was continuously developed for another 10 years beyond the cut-off date be allowed to race in its more modern guise. I'd rather it was returned, in large, to an earlier period in its history that fits within the cut-off date.
