I joined when I decided that my Triumph Stag was becoming a pain and wanted a car with real character.
Through joining I meet Jim Richardson who was then the Secretary of TORMOG and he helped me with the decision to purchase a 1991 +8.
Other than that we go to the local meets as often as possible and have been on the clubs Le Mans trip so in my opinion the cost of membership is nothing in comparison to the opportunities to meet and learn from more experienced owners.
However I do think the club mag is quite poor but assume they can only print what they are given so maybe it's time for a change there.
