This is a person in Kingman, Az. pretending to "have a serious buyer for your car". he photocopies a handwritten note and then tears them off to look like it was only meant for you. So people call him thinking someone wants to buy their car. Its illegal to do this in the city. They are probably related to the car dealers or just doing it by themselves, nontheless they are scammers! Their phone numbers should be posted all over the internet as scammers!
