Just been quoted over £600 with a £6000 excess for track day insurance for this event (series 5 aero) so I guess I won’t be going but looks like it will be a great event
My experience has been that most of the specialist Morgan insurers don't charge extra for "non competitive, untimed" track days, as long as the event is pre-advised. Certainly that was my experience with the Williams Charity Track Days at Castle Combe.
