I (for one) would rock this one with pride, just as it is.
Everybody is going to have an option-- but if it can't be the "Clown Car Club of America", then "PCCA" works well enough because it's an obvious thumbing of the nose at the PCA, which gets it bunches of style points. I'd just like a creepier clown and a tow truck in the crest.
If not a tow truck, then perhaps a hubcap flying off the clown car. I don't know, I'm not the artist.
If anybody can do it, it's our man Sacto Mitch!
