I've been hunting for a specific car and paying a lot of attention to the various venues, eg BAT, eBay, CraigsList, Facebook Marketplace, etc. and I've made the following observations:

BAT seems to have the nicest cars and most honest bidding and discussion, which is mostly due to the heavy curation of that they let in the door. It's also a great place to lurk and learn.

eBay seems to have the worst cars; the business model seems to be "throw it out there and wait for some sucker to come along." There's some 20-footer cars that the seller would probably prefer to avoid the scrutiny of BAT's peanut gallery, and there are others I've seen that are literally scrap metal.

FB marketplace seems to be the home of dreamers saw one go for 6 figures at Barrett Jackson so they think the beater POS they have in their back yard is worth that much, but they can't be bothered to drag it out into the light of day to take good pix.

Craigslist is for the people who think posting the same car 200 times with a slightly different description in each ad will somehow sell the car.
