Craig's List is a funny place - in Michigan, we sell a TON of used cars; have sold our various RVs through it, and in general it works great. In Florida, it's another story - people seem leery of it.
Facebook Marketplace is good, if you already have a FB account. Also - if you have a "Nextdoor" website for your area, that's a good resource.
I do know that in Michigan, at least, if you sell a titled vehicle, etc through a consignment, the selling dealer needs to have your title signed over to them. That's going to require some trust on your part. (It may be different for other states)
