Biting the hand that feeds them ?
A strange comment.
I suspect that it's reference to the high charges for the event.
The problem when you involve 'professional' marketeers and events organisers, they will look at the cost of new Morgans and the demographics and pitch a price to cover their costs and make a profit.
Morgan make cars, not organise events although that's what they did in 1984 for the 75th anniversary. I believe that Peter Morgan hired Mark Aston to help organise MOG84 and what a brilliantly run and friendly event that was and without silly high prices.
Rather that use the phrase 'bite the hand' I'd suggest that Morgan need to remember who the owners and the club are and what they bring to the party. Every time someone in the street sees a Morgan, new, recent or a beautifully maintained old model from the 1950s or 1960s, it helps create the desire to aspire to own one. To most people, they all look the same regardless of age.
Demographics and market segmentation really don't work well for Morgan ownership where for many a Morgan was bought many years ago.
