Usage
Hagerty provides coverage for collector vehicles that are used on a limited basis — e.g. club functions, exhibitions, organized meets, tours and limited pleasure driving.

Storage
Collector vehicles must be stored in an enclosed and secure structure when not in use. Qualifying storage locations include private residential garages, private pole buildings or barns and rental storage units.

Seem to be similar rules?

State Farm costs and terms-of-use are so good that I'll gladly pay $50 for an appraisal (for each vehicle).
