Get a GPS and get rid of the OnStar.
Think about it...
If they can open your car door, they can lock it.
They always know where you are.
How long are they keeping those records?
It's just spooky to know someone can track everything you did - how many years from now?
I have been thinking of getting a GPS. Now that you put it this way, maybe its a better idea than I originally thought. Although, I do not have anything to hide.
