I bought mine from a craigslist ad
We went, we saw and took notes, did some research.
Agreed on a price and we went to the bank where the funds were exchanged and the title transferred ( AZ requires a Notary on a title change, which does much to cut down on fraud)
a very fair deal both ways
While I looked at distant ads online and "Trader" it was only to research features and compare "comps" to determine value
In my world of vintage guitars, I do face to face cash transactions unless dealing with a person known to me.
