The company ADV has definitely been shady. Lots of stories about their dealings. I worked with a dealer here in San Diego, Automobile Connoisseur Group. I went with the ADV 10 DC for my M5 and I couldn't be happier. ACG is very aware of the issues with ADV. They do a full inspection of the wheels and send them back. No payment until the wheels meet their quality standards. That being said, I would understand if someone avoided them.
