At a guess from being at a few Morgan do's most Morgan 4 wheeled owners will be in their late 50's or 60's
37 and had mine at 34....proved you hypothesis!!
Sample bias Stewart. What you are observing is the self-selecting subgroup that opt to go to organised events (and has the time to indulge such hobbies) not the overall demographic of ownership. You will find the younger generation eschew organised events, especially anything MSCC.
ps bought my first at age 45
