First of all I am a mk2 Fiesta owner.
I think that the forum should allow newer fords, but have them in a section i.e.80's Fords. I don't think this would change the identity of the club but just add further like minded people to the forum.
In terms of at the shows, it would just make the stand bigger and you could group the cars by age/ model in different areas. To be honest I think most people would just carry on showing with other groups.
It would also make the osf drag challenge a bit more exciting if we could take part.
With new people comes new ideas and progress, new topics for discussion etc.
Either way I will continue visiting the forum.
