I recently posted my car on AutoTrader.ca and I recieved a call on my voicemail. It was a fellow who said his name was Brad, and that he had been trying to call me a couple times. He said he saw my ad for my car, and that he can get it sold for me for a fee. He told me because of the obvious quality of my car, he could "Guarantee" a sale.
When I called back, Brad was unavailable, but but April would help me. When I asked for a business number and address and more information, she hung up on me.
This is an obvious scam for me to give them a couple hundred dollars up front.
