how do i script to show the car dashing effect? - unity3d

Question

Actually, I'm developing an endless 3d car runner game made a city view where I'm showing some parked cars so basically what I want is when my player car collides with the parked car I want the parked car to rotate some degree and get back to 0 degree or original position how it was before.
I just wanted to lift the parked car and again should touch the ground back to normal. So this will show some realistic effect in game view.
since I'm new in unity development your help could really help me alot.
what I tried so far is :
void OnTriggerStay(Collider other)
{
if (gameObject.CompareTag("ParkedCar"))
{
Debug.Log("ParkedCar");
Quaternion from, to;
float inputValue = 0;
inputValue += Input.GetAxis("Vertical") * 10 * 1;
from = transform.rotation;
to = Quaternion.Euler(0, inputValue, 0);
gameObject.transform.rotation = Quaternion.Lerp(from, to, Time.deltaTime * 10f);
}
}
even i have tried this
void OnTriggerStay(Collider other)
{
if (gameObject.CompareTag("ParkedCar"))
{
gameObject.GetComponent<Rigidbody>().AddForce(transform.right * 100, ForceMode.Impulse);
}
}
trying this but i cant get my parked car collide again on ground. pls help me here.

If i understood you correctly you can implement this with a coroutine and OnTriggerEnter instead of OnTriggerStay like this:
private bool isDashed = false;
float time = 1.0f;
void OnTriggerEnter(Collider other)
{
//Assuming your to quaternion is correct
if (gameObject.CompareTag("ParkedCar") && !isDashed)
{
Debug.Log("ParkedCar");
Quaternion from, to;
float inputValue = 0;
inputValue += Input.GetAxis("Vertical") * 10 * 1;
from = transform.rotation;
to = Quaternion.Euler(0, inputValue, 0);
StartCoroutine(DashingCar(from, to));
}
}
IEnumerator DashingCar(Quaternion from, Quaternion to)
{
float elapsedTime = 0.0f;
while (elapsedTime < time)
{
gameObject.transform.rotation = Quaternion.Lerp(from, to, elapsedTime / time);
elapsedTime += Time.deltaTime;
yield return null;
}
isDashed = true;
}
