I want to make a car lift but I have no idea how to make it work

This is my script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;


public class CarLift : MonoBehaviour
{

    public GameObject min;
    public GameObject max;
    public GameObject[] Car;
    int i;
    public float liftSpeed = 20f;
    Rigidbody2D rb;

    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }

    
    public void pointerDownGreen()
    {
        FindObjectOfType<AudioManager>().Play("carLift");
        Debug.Log("DownGreen");
    }

    public void pointerDownRed()
    {
        FindObjectOfType<AudioManager>().Play("carLift");
        Debug.Log("DownRed");
    }

    public void pointerUp()
    {
         FindObjectOfType<AudioManager>().Stop("carLift");
         Debug.Log("Up");
    }

    private void OnTriggerEnter(Collider trigger)
    {
            foreach (GameObject Cars in Car) 
        {
            if()
            {
                break;
            }
            else
            {
                continue;
            }
        }
    }
}

I want to make that the car stop when it touches GameObject Min or Max but i don’t now how to make the car to move up and down

The car should move when you press a button (upBtn and downBtn).

if you want to make your car go up you could do:
rb.velocity = new Vector2(rb.velocity.x, liftSpeed);
this one can be used for adding a force and letting it go up, you can do rb.velocity = new Vector2(rb.velocity.x, 0);
but if you want to go up a little bit each update and stop whenever you want the bottom one is one way of doing it too

transform.position += new Vector2(0, liftSpeed * Time.fixedDeltaTime);

and also in your onTrigger if statement there is no condition, this gives errors, you could do if(cars.CompareTag(“YourTag”))
