Longwood Inc AKA "Brad" Offered to sell my car I had already sold on Craigslist Internet

I received a call from "Brad" on my voicemail yesterday, telling me he is leaving a message because he has been trying to reach me. Not true, I have Vonage and you get a detailed list of all calls and voicemail on your online account that is permanent unless you delete it. This is the same scam regarding offering to sell my car, for a "small upfront fee". I had already sold the car days before and had removed my listing. This is a wake-up call to all of us who use Craigslist: do NOT post your telephone number. This is the first time I did, and I am very sorry. Usually I only use the email option, with excellent results. I am truly sorry for anyone who falls for this obviously underhanded scambogger.
