Sorry that you had so little response for your efforts, Thomas. I would have come for a few hours but had a prior engagement that day.
Trying to organise an event can be very frustrating
In hindsight, I think you would have had more interest by using F/TF forums to advertise the event. MG owners clubs run their own events & F/TF's are in the minority there.
If you are still interested, start by doing a small meet for F/TF''s, with a run around your area probably with.lunch at your pub at the end.
Hopefully, this will bring together F/TF owners in the SW, who want to drive their cars & meet other people with similar interests.
Let's face it, events are thin on the ground & need supporting.
I will be putting up an event soon in the W/Mids area & hope I get a better response
