Overall premiums (including comprehensive/theft coverage) vary widely by geography - even different zip codes in the same town can have significant price differences due to local experiences. State regulation of insurance companies and rates vary as well.
Having said that, I, too, found my State Farm agent more than happy to write the policy and price it based on MSRP because there was nothing on their system. It could stay that way awhile until the industry gathers some statistics on accident rates, repair costs, etc. for this still very, very new vehicle.
