[1.48] How do categories work on the market?

I would like to explain the Market.
How to define a category for the car. As a control if it will be part of the category “Budget” or “Luxury”, for example?

Thank you for any help.

If you look at the screen where you set up the specification for the car you’ll find an area in the top right where you can adjust the price. By adjusting the price of the car you’ll see the category that it fits into changes.

Thank you.
