I am a business analyst with a major insurance company. Currently, I am working on a project, which will help determine whether my company decides to start insuring collector cars. Specifically, I have been tasked with determining the market size for collector car insurance. I would like to know whether anyone in this forum knows of any studies that have been conducted to determine the number of collector cars or collector car owners in any geographical area: county, city, state, etc. Please provide me with a link to this data in your response. Thank you in advance for your assistance.
