From what I've read they see someone selling the right kind of Bronco, make them a cash offer, then put it up for sale for about twice what they paid for it. They fudge the facts because their sales are online and the buyer is not going to see it in person. They make a buck and go on to the next one. After their name gets too bad to continue, they change the name of thier company and start over. Repeat.
It makes sense that if you have $20,000+ to spend on a hobby vehicle, you would spend a few hundred to fly out and look at it in person. Never purchase a vehicle online from someone you don't know unless you have seen it in person. You could also pay a consultant to look it over for you.
