I've been watching this thread and thought I would offer my thoughts.
The only reason that I drove in CM for 4 years is because Greg Vincent asked me. Half way through a season he asked me if I wanted to drive the car for the rest of the year. No charge. Just try it to see if I like it.
Naturally, I jumped at the chance, got hooked, and co-drove for the next three years. His old car is for sale and I would jump at the chance to own it, but I have two daughters now that take financial precedence.
Someone that is not familiar or has not driven a C-Mod car (or any Mod car) is not going to be as quick to jump into owing one. It's easy to find parts for the STS Honda if that's what you decide to buy. Finding parts for a Formula Ford is not perceived to be as easy to the newbie.
If CM is to grow, it is going to take active invitations by the current CM car owners. I'm not saying that you have to give a free ride to every Tom, Dick, or Harry that autocrosses, but find someone that looks promising, has been driving for a few years, and offer them a ride in the car for an event.
