It's a scam that moves around the country, and I have seen these criminals here in Dunwoody. A group is active here in the Dunwoody / Sandy Springs area this week! Just recently a local person was victim to the notorious "I can fix that dent for you" scam. A man will approach potential targets (you) in a parking lot or maybe even in your driveway. The man may have props with him (a female, a "hungry" child, whatever).
DON'T LET THEM TOUCH YOUR CAR.
STAY IN YOUR CAR, LOCK THE DOORS, PICK UP YOUR PHONE. DRIVE YOURSELF, YOUR PASSENGERS, AND YOUR CAR FROM THE AREA IMMEDIATELY!
CALL POLICE IF THEY FOLLOW YOU OR THREATEN YOU.
The man will offer to fix a dent, and claim his repair is far less expensive than an auto body shop. They will most likely do poor work then shake you down for cash. The 'repair' they perform will actually make things worse for your vehicle. They will follow you and harass you. Just like we learned in kindergarten, don't talk to strangers.
Simply Google the terms: Gypsy dent repair scam' and you'll find plenty of stories
HERE is the type of report you will see all over the Internet.
