I think the best defence to the main risk of ageing owners is an active club to ensure we can get younger owners interested in our cars. I think this is what has happened with the NSX community in the US they seem to have a larger proportion of younger owners, no data to back this up just a feeling based on mainly facebook posts.

We have a club www.nsxclub.co.uk and many events planned for 2021 and if we can get good attendance this will be a start at getting our special and rare cars better known to a younger audience. Rarity works against us in the transfer of interest to younger generations.

For my part I doubt I will outlive the availability of petrol so I am not that concerned about this risk. Porsche will start testing green synthetic "petrol" in 2022 so this could be the answer:
