Follow an elliptical waypoint.

Hello, I am new to the Unity-3D.

I have placed the 3D model of the car on an elliptical plane. On which the salesman has to move, with nobody controlling it. I have to create an elliptical way-point as he has to follow that until a customer(user) comes to the car.

The question is: How to follow that elliptical way-point? Can anyone, please, help me on the scripting.

Thanks.
