Just an update guys. Shannon's has decided to pay me out instead of repairing the car. The interior was completely stripped (except the dash), boot was totally stripped, boot lid and rear spoiler were gone, bonnet and front bumper were gone, some of the engine bay had started to be taken apart.
In other words, the thieves didn't waste any time.
On the bright side, at least the two thieves were caught red handed and they will likely get convicted. Oh, and this might be a good excuse to get an R34 GTR sooner rather than later.
All I have to say is that Shannon's was a pleasure to deal with through the entire process. They had top customer service and I will definitely insure cars with them in the future.
