problem whit Instantiate Prefabs position.

Hi everyone. I have a GameObject (which is a vehicle that moves in the scene). He has a child a gameobject. In that I put a trigger type collider box and a script. The script says that by colliding, I instantiate another vehicle (with other features and that is a PREFAB) while the original vehicle is destroyed:

 public GameObject PrefabObject;
 public GameObject destroyOriginalObject;

 void OnTriggerEnter (Collider other) 
 {
     if (other.gameObject.tag == "Player") 
     {
         Instantiate(PrefabObject, transform.position, transform.rotation);
         Destroy (destroyOriginalObject.gameObject);
     }            
 }

This works but at the moment of Instantiate the new GameObject Prefabs, in the scene it is positioned very far from where the original GameObject is (destroyed). But the strange thing is that when I see the transform in the inspector it has effectively copied the same position and rotation but in the scene it is positioned elsewhere. How can I fix it? Thanks a lot!!!
