For a very small amount of detail information, the standard way to display details would be to have a + beside "Interior", which when clicked slides down to display the extra details.
For larger amounts of information you will probably want to have an arrow (pointing off screen to indicate another screen is available) beside "interior", which takes you to a seperate details screen when clicked.
For linking "General" to "Categories", you need some kind of affordance indicating that the user is leaving the overview and looking at more advanced / detailed options. A common way to represent this is with ellipsis.
An ellipsis works well because it’s a common mark used in the english
language for omissions and unfinished thoughts. At a cognitive level,
users will understand an ellipsis affordance to mean that there are
more options available to complete the task that aren’t yet displayed.
The ellipsis tells users that the action is not immediate. This allows
users to click a button or menu selection to explore the different
options behind it. Without ellipsis affordances, users will assume
that every action and selection is immediate when every one is not.
