We have our PC lumped with our cars through Hartford, one policy, all vehicles. Hartford does a nice job in that they know we can't drive more than two vehicles at any given time, and they also understand that our PC is a "seasonal use" vehicle, and my sports cars that come and go all the time are treated like our PC.
With full coverage (whatever that is defined as) we pay a fraction of those numbers, but after reading through this thread, I wonder what value Hartford declares our 2007 PC to be.
