I do too, sell occasionally on CL, I have had good luck, sold a snow blower and a saw this week, last summer I see a nice John Deere riding lawn mower, after a few text, guy said he take 1k bring trailer, asking price was 1100 so I went and looked at, pulled up nice house, lawn tractor looked and ran great, so I said ill take for 1000, guy said did you bring cash, I said I did, he said come on in, so went in we sat at his dinning room table, he had all paper work he had, and owners manual, then ask me if I didn't mind read this and sign it, it was a 2 page document relieving him of anything know to man kind, I read that couldn't help but laughed, (were talking 1000 bucks) I asked if he was a Lawyer he said no, I am a book keeper, but know how these things work and come back on ya, I signed paper releases him from everything and anything, all turned out fine, but thought that was very strange, weird and funny
