I has been almost 2 years since this thread was last active, but I thought I would provide an update since a critical piece of advice was never given.
Back then, around the time this thread was active, I received a letter from the dealer asking for their "$1000 deductible". Shortly thereafter, my insurance company requested from the dealer a copy of their Garagekeepers Policy as proof that their deductible was indeed $1000. We never heard from the dealer again; end-of-story.
The dealer could have said their deductible was $1000, $10,000 or $1,000,000. Regardless of whether it is my fault, or responsibility to make the dealer whole, the point of this thread was to proceed with due diligence. None of the thread contibutors, particularly Zigner et al., were capable of providing any such useful information. If they are still around providing advice, I would take it with a little more than a grain of salt. Good luck!
