I have offered suggestions to those on the SAS list, but the decision to make a formal complaint to law enforcement or to hire private counsel to pursue damages has to remain with them. There are pros and cons of both approaches. After all, the guys in the queue are the ones with money to lose. I was in the same predicament prior to getting my car.
On one hand, you want to make the guy who took your money suffer, but, on the other hand, if there is even a tiny chance of actually getting your car, you don't want to upset the tenuous financial balance of the "company" by calling the cops, since this guy knows how to scam the system. I don't know the answer, but, since I have my car, such as it is, it's a rhetorical question only for me. The final answer will need to come from those whose ox has been gorged.
