Selling towers - keep getting bad actors/scammers when doing local pickup only.

In recent months I have sold more than 1 item via US Audio Mart & Facebook Marketplace and used the local pickup option. You get all walks of life. Their cash money works for me. 
Never an issue. 

I've had really good luck on Craigslist.   The last few items I brought to the prospective buyers , I made it easy for them to listen and buy.  

I sold a pair of Omega speakers in April , I brought them to RI .  I live in Mass but it was worth the 25 min ride.   We set the speakers up, huge smile on his face once the music started. I knew I wasnt going home with them.  

Was worth the minimal effort.  It's a tough climate for luxury items and toys .  I can't remember if that sale was Craigslist or FB marketplace.   I don't use Facebook but sometimes I'll have my girlfriend list stuff on marketplace for additional exposure 

Only good experience with local sales on Audiogon...though none past 1+ years...

Have a conversation with them about the loudspeakers and their system. When they come to pick them up let a friend know and arrange to contact them after the sale.  The buyer with $4k in cash has more to worry about being scammed then you do.

Selling tower speakers and other high-$ gear locally just takes more time, usually to find a buyer.  Any local ad I make always includes "Cash or Zelle in person" in the ad.

In y experience, the serious buyers are usually easy to spot when they ask a simple question like, "When can you show/ demo these."  On FB, you can also see their profile, what town they live in, if local, sometimes they list their employer, etc.  You can see that they are a real person and perhaps someone with means if they have pictures of their other audio gear in their FB page.
