Implement CarQuery API into WordPress

I’m using CarQuery API WordPress plugin on my wordpress website to display years, makes, models, and trims of the vehicles. The problem is that it only shows up to 2017.

WHAT DO I WANT: I purchased a CSV file from your website and I want the plugin to host it on my server and grab data directly from it so there is no delay/tech issues.

Is there an easy way to do it? Or when is the 2018 info going to be available?

Thank you!
