I'm glad I don't use CL much, although I do like some of it's features. The fact is that there a several other free places to list BST ads including used cars which are equally or more effective than CL. I'm hearing a lot of rave reviews over Facebook (ugh) Marketplace these days and have even bought some stuff off it.
I seem to look at FB more than I do my traditional "hunting grounds" lately, but that might be more because I'm avoiding them as I don't have time, space or funds to make superfluous purchases at the moment. The last time I went looking at something it led to other things that eventually "cost" me $20,000. But it's all good...significant business expansions this year!
