hope everything goes well, and yes take pictures, inside and out, your going to need them after if you not happy with the work etc, also find any pictures you have of the car before the problem occured
if your going to keep the car, and live at the same property, it might really be worth thinking in to getting a decent home alarm, and a camera set up, i know camera set ups aint much any more, im in the process of getting one togther my self, after reading all this, id rather spend £500 on a really good set up, than spend £500 on excess. Plus it helps in more ways than one, the cameras there for any kind of problem, and should make your mrs feel more secure at home, as its not just the car, its the house that was a target aswell.
maybe on the next car get a tracker? i know its headache and more money spent, but theres trackers that are mobile, you just stick it any where in the car, and its not coded to that car, so could be an investment for all your cars, i had one in the past, and you just log on to the net, and you can locate it
Just some of my thoughts to the matter
