Just sold my wheel fairings to a local guy that saw my ad on this facebook group. I listed them on the Cessna 150/152 Club forum back on 11/2019, and over 19 months got no offers. I had reduced the asking price from $500 to $400. I listed them on the facebook group a couple of days ago at $500 and had two offers almost immediately. Delivered them today for the full asking price.
So my guess is that you will get a lot more eyeballs on your listing if you put it here also:
