Are you trying to do with with code? I remind you StackOverflow is for programming. For other game related things there is gamedev.stackexchange.com.

If you are doing this with code - and given that I don't know how the scene tree looks like - I suggest using look_at. Something like this (code for the Camera):

look_at(car.global_transform.origin, car.global_transform.basis.y)

There car is a reference to the car. I can't tell you how to get one without looking at the scene tree, beyond that you can probably use get_node. So car.global_transform.origin is the position of the car in global coordinates. And car.global_transform.basis.y is the direction towards the up of the car.

The method look_at needs an up vector because there are infinite ways to look at a given point (rotate around the view line). Thus, we do not want an up vector that matches the view line. For example, Vector3.UP won't work if the camera is looking directly up or directly down.

And if you just want to rotate this in the designer. You can use the gizmo you see when you select it. You can drag the blue ring until it is aligned correctly.

The de facto standard for this gizmos is that x is red, y is green, and z is blue (this is true in Godot, Blender, and plenty of other software). So the blue ring rotates around the z axis. You can also find that rotation in the inspector panel, look for rotation degrees for the z under transform.

I remind you that if you place the Camera as a child node of another Spatial, it will keep its position and orientation relative to it. So placing the Camera as child of your player character (e.g. a KinematicBody) is often good enough for the early stages of development, as that guarantees that the Camera follows the player character. No coding necessary. You may want a more elaborate Camera control later, which would require some code.

Since you mention "spinning camera", perhaps you want a Camera that orbits around a point. The easier way to do this is to add an auxiliary Spatial for the point the Camera rotates around. Let us call it Pivot, and rotate that. For clarity, I'm suggesting a setup like this:

PlayerCharacter
└ Pivot
  └ Camera

Here the Pivot follows the player character. And the Camera follows the Pivot. So moving the player character moves the Camera, and rotating the Pivot makes the Camera orbit. This is just lacking some code to make the Pivot rotate. For example something like this (code for Pivot):

global_transform.rotate_y(Input.get_axis("camera_left", "camera_right"))

Where "camera_left" and "camera_right" are actions configured in the Input Map (in Project settings). Which reminds me, you can set actions from code with Input.action_press, so there could be code somewhere else (e.g. _input) writing these actions from mouse movement.

Camera Control does not have to be hard.
