Two weeks ago we listed our older van for sale on CL. I think all the responses we got were scammers. All were either in the military reserves, out on a forestry job, or something that they would need to send an "agent" to pick it up for them. Wanted our paypal info, etc. When I said we were dealing in cash only I didn't hear any more from them. One said she wanted to surprise her son in Romania with the van. How crazy! Ship a '97 Van to Romania!?!?!?
My brother-in-law built a whole garage with stuff he bought mostly off CL and sold the leftovers back on CL and had a complete garage for real cheap. So there are good things going on with CL, but you've got to keep your guard up there just like anywhere else.
