How to make camera have same rotation as an object but with an offset (Unity)

So i have a car and a camera and so far here is the camera script:

 public GameObject car;
    public Vector3 offset;

    void Start()
    {
        offset = transform.position - car.transform.position;
        
    }

    // Update is called once per frame
    void FixedUpdate()
    {
        transform.position = transform.position = Vector3.Lerp(transform.position, car.transform.position + offset, 0.8f);
    }
}

This makes the camera smoothly move with the car, but now i want the camera to also have the same rotation as the car but with the starting offset.

You could just the "same" way store the original delta rotation like

Quaternion offsetRotation;

private void Start ()
{
    offset = transform.position - car.transform.position;

    offsetRotation = transform.rotation * Quaternion.Inverse(car.transform.rotation);
}

And then later

void FixedUpdate()
{
    transform.position = Vector3.Lerp(transform.position, car.transform.position + offset, 0.8f);

    transform.rotation = Quaternion.Slerp(transform.rotation, car.transform.rotation * offsetRotation, 0.8f);
}
