Yep 8-9 years ago we were selling our daughter's car for her. I put an ad on ebay or craigslist, hit send, hopped in my truck to run errands. 2 miles away my phone started ringing. The first 5 calls were all some variation of calling for a friend in the military, can I come look at it for him? etc etc. I have no idea how the scam worked but over the next couple of days maybe 10 more similar calls. One of my errands was to go to the DMV office to see if I should get the car titled in my name vs daughters to make the sale easier. Turns out the guy I talked to had a son looking for a car and he bought it a couple days later. I was really, really glad to take that ad down.
