Two short stories to relate, as a buyer:
Went to buy a tube amp. Drove an hour, got there, didn’t work right. Drove home. 15 minutes in got a call from seller who called a shop 20 min from his place who said it was likely just a tube and to meet him there. So 35 min later I was at the shop - when the seller decided he no longer wanted to sell the amp. Now I had an hour 20 min drive home. That’s 3 1/2 hours of just drive time, to get home with no amp. Infuriating.
Second story: I went to buy a couple guitars for big $$. Seller emailed and said before I make the long drive, the price was firm. He lived 90 minutes away. I said “ok, but without seeing the instruments in person, I’d not be able to determine their value.” I followed that up with “at worst, I take a long drive for nothing”. When I got there, the instruments were as described, and I presented him with a lot more cash than I felt comfortable ever carrying. Then things got relaxed. He invited me in and we chatted and he showed me other guitars for the next hour+.
Bonus stories: As a seller, I’ve had buyers not show up. Or they text they are on their way or running late and then an hour later another text saying something came up. Or just a complete no show.
I’ve met buyers at public spots half way. That can be tricky in LA traffic with each person driving an hour, hoping the other party is on time and shows up at all. (hint: choose a place where there is stuff to do while waiting, so if you have to wait an hour or the guy doesn’t show, at least you got to do something interesting.)
I had one time selling something when I was supposed to meet the buyer halfway, but fell ill before leaving the house. The buyer was on his way to the meeting point. I texted him I was very sorry and couldn’t meet him there, but if he wanted he could drive to my house and I would take $50 off the price. He agreed. He got a very good deal, and I didn’t have to spend the next day cleaning out human waste from my car’s interior.

Win-win.
