It seems like a convoluted way to increase membership and raise revenue. Why not just raise the membership fee by $10-15? What is the number of current members?
The 2 widows that joined to sell their cars aren’t likely, in my opinion, to renew their membership. Anyone who joins to sell a car would be selling into the focused group who are probably already members, so the new owner would not be a new member, and the seller might not renew after the sale.
I’ve seen Avantis that are for sale on Hemmings, Classic.com, and numerous other sites for months. That’s a good indicator that the price is too high. I can’t be certain but it’s likely that those sites get much more traffic that this site, particularly the For Sale section.
I’m not trying to be your rain cloud. It just seems that if an effort is going to be made to achieve your stated goal, we might see more productive results by informing non-member owners of the benefits of membership through direct contact, as you’ve done, or by attending car shows and approaching Avanti owners to ask if they are members. That is also a lot of work, but if we can get as many members as possible to take some of those steps we could increase the membership numbers. That’s would provide a steady flow of revenue as long as those members renew each year. Revenue from ad placement on the other hand would be variable.
