I have made a note for my next-of to contact a specific Bike Forums member in the event of my demise. That individual would receive a PM requesting relative values of my seven remaining bikes; in return, they get all my spare parts and tools gratis
No, the person doesn't know they've been so designated, but they are plenty knowledgeable and were chosen because I know they can be trusted.
Hopefully it'll be another 20 years or more before that PM hits your inbox...
