The IOCGB is run as a Limited Company and provides its members with access to both new and used spares. New members enrolling pay a subscription, plus a once only registration fee which funds the purchase of spare parts, including secondhand and used parts. The club has several tons of stock.

The club also attempts to bring together Isetta owners either by way of regular meetings or rallies, or simply by way of the club magazine.
