I depends what you told them when you called them.
If you told them that you were going to turn it back into them at some future date, they may have determined it to be prudent to repo the car now before something happened to it...
You would be surprised at what people do to a car that they know is about to be repo'ed.
I am not saying you would do anything. I am saying that it was in the best interests of the car company to get it sooner rather than later.
Did you tell them that it was a probability that you were going to turn in the car?
