Part of the attraction for a potential new member is being able to own one of the cars covered by a club. Considering the total number of prototypes built (there was no actual Tucker production reflecting a finalized bill of materials for parts, assemblies, etc) that kind of closed the doors and the increase in sale pricing made the door close even more for the average enthusiast.
Barbara and I have lived in various areas of the Eastern United States and now in Washington State. We've noticed that K-F cars unlike a lot of other makes of the period draw people's attention because you rarely if ever see them. When they talk to us we tell them why we got the Henry J, availability of parts to keep it going, and how being in the KFOCI further helps support & ideas on restoration/maintenance situations, etc. We brought in at least 1 new member through our interaction with spectators. I personally feel this is where the future of the club and membership growth lies. Show people that cars are available at affordable prices, parts can be found to keep those cars on the road and in proper shape and that the information and technical assistance available through the club (not to mention other parts sources) is well worth the cost of membership dues.
