Display post content based on user's selection from dropdown

I have a set of dropdowns pupulated with auto-moto data, eg. Select car brand: (list of all brands), when I select eg. Brand1, then I get to select Car model from another dropdown, ... etc.

Now I have created few posts, each post has some pricing information for the selected car. What I want to do is based on the selected car, I want to show specific post.

Currently I was able to get all the dropdown settings with WPForms or Gravity Forms, but they do not provide a way to display post content based on the selection. It's always just a form submission, which I don't need.

Is there some other easy way of doing this?
