I hope that membership of the VOC is not motivated by just financial incentives. the real bonus for me is sixty years of friends,racing,meals, club nights, foreign visits and companionship. ( and that's from someone who was too busy riding the damn things to go to a rally for the first 15-20 years)
May I add, if for instance you owned a Douglas, Scott or a Velo and were Not in the respective owners club, you would not be able to even buy spares from the clubs arranged sources, let alone a 10% discount.
