How safe is the dealer with your stuff?

Navyskcs I feel your pain, but in this case CW is within reason, rare I know. Had you parked in any parking lot and been hit by any passing vehicle your recourse would be that person's insurance. I see no real difference in the CW parking lot, UNLESS the passing driver was a CW vehicle mover in which case of course they would be liable. Once CW takes possession of your vehicle and moves it about, it is their responsibility, but not before that.
Please note IANAL (I am not a lawyer), I just play one for kicks now and then.
