I don't agree. Your never stuck or cuffed to a dealer. There independently owned. Independently operated. Independent customer service. Now there is a good chance the car has been flagged by the VIN. But that may not be the case especially if there no lawsuit or such associated with the car.
If I was in the OP's dilemma I would go in my car and press the sos button try and get a free tow to the dealer who does business with his aftermarket shop and play dumb until further questioned. Never lie just say as little as possible. If they ask tell the truth. Bla bla and see where it unfolds from there. That seems to be his best bet currently.
