I don't understand why you are getting all worked up. You have a brand new car that you are driving for half the cost, free xm, and no penalty for mileage. If I where you:

Go on that road trip
Stop calling them
Enjoy the loaner car


If they are trying to avoid you, let them! You have the better end of the deal!
