How can I monetize my database?

I’ve scraped a car marketplace website where people sell their cars directly. My scraper is automated and can continue to scrap this site for as long as it remains undetected.

So far I’ve gathered the data of 12k+ listings and I have all the usual information about the vehicles and the name and phone numbers of the sellers.

I can know which are the top brands, models, car styles, the top sellers. I can know how many vehicles are listed per day, and so on.

So far my idea for this data has been to use it for a market study but I know there may be people or companies interested in this.

I know I can provide an API to this data or sell statistics but I would like to know how would you monetize it and for how much?

BTW, the website I scraped is not from the US so I don’t have US specific information.

Thanks all!
