For my insurance company, every two years I need to provide a valuation to maintain the agreed value basis of insurance. I ask the servicing dealer to provide this and this has been done for no charge by both the factory and Williams as part of the annual service.
Personally I would expect to be charged for the valuation if I were not having a service at the dealership.
