Help with trigger zone

Hi, I have a little car game, something similar to Hill Climb Racing, and I have a trigger zone at the end of the level. I tried some scripts that I found arond, but nothing worked. This is what I need:
I have the car named “PickUp” and at the end of the level the trigger. When the car enters in the trigger zone, I want to load the menu. I tried to do a scri’t myself, but didn’t work.
Thx.

Give Your car object (the one with collider if Your car is made from more parts) a tag “Car” and try this: (to add a tag, go to Edit->Project settings->Tags and Layers, and then in Yor car gameObject inspector, select Tag to Car)

class LevelEnd : MonoBehaviour
{
 void OnTriggerEnter(Collider c)
 {
  if(c.CompareTag("Car"))
  {
   Application.LoadLevel("Level Name"); //Or Application.LoadLevel(0); where 0 is level index in build settings
  }
 }
}

And attach this script to trigger.

Hope that helps,
Paul
