Thanks for the great feedback. Interesting read. The main thing about facebook market place is that it is free. Just like craiglist. So there is zero harm in having exposure. I happen to work at a Honda dealership and think Honda vehicles would perhaps get more interest, but I could be wrong.
If I make one sale, that free advertising will cost average into the cost of all my sales leads. So I only see a positive with using the market place. I only want to make it easy, hence the question of a vendor offering the service.
350 million users .. think about that..
