Question of the day (my mother made me do it)

The Question of the day is:

If I were a part of a car I would be...

1. A Seat Belt


2. A Sunroof


3. A Gas Petal


4. A Horn


5. A Spare Tire


6. A Navigation System

I would be a Spare Tire beacuse a spare tire is there when you need it. I try to be there when someone needs me.

What would you be?
