That's legit. It's a firm NO. Same thing I've heard over and over.
One of you has to live near one of these dealerships. Why don't you mosey on over and take a few pictures of the OBD II's they have in stock? Seems simple enough. After all everyone has inventory right? I tried to at my local Carmax but they had never heard of it. In fact non of the dealerships I called had heard of it.
