I JUST got a call from 'Julia' and decided to google the number. I have my car listed in the Bargain Finder & Auto Trader (I'm guessing that's where they got it from).

This Julia is a scammer who has called me repeatedly with the line that she already has a few buyers for my car.  When she calls she acts like a private buyer and gives no indication that she's representing a service until later in the conversation.  I told her I'd gladly send her a check AFTER she sells my car for my asking price.  Nope.  You must pay ahead of time.  This is a rip off attempt.  I have told her to stop calling me yet she continues to do so about every month.
