Agreed, I just don't advertise anymore but keep the stuff I might need.
Just threw out about 50 trim pieces, windshield, side, hatch, etc after advertising in a half dozen areas for a couple years.
A week later someone calls me about the windshield trim. He was noticeable bent that I tossed them, saying he's been searching forever for that particular trim. I asked him what it was worth to him, he said $15. Really? So you've been searching forever but only willing to cough up $15. I simply said my crap has been on CL forever and he obviously needs to expand his searching techniques. This guy gave me great insight, so I tossed more crap in the garbage.
