Sorry to hear that sucks! Worse case scenario they don't retrieve it or they do and it's a right off.
Personally I wouldn't want my vehicle back case I know it has been abused and the years of issue and problems are never ending. This probably was your "baby" and I respect that but as long as you have receipts or proof of add ons your insurance company will probably settle on a pretty good value and you can always get another new toy

Someone tried to steal my 2003 Yamaha R6, I was was and took precautions buy having it cable locked to the rim of my car with all 4 locking wheel nuts on that one rim
They did enough damage that it was gone for 4 weeks being repaired and it was never the same after that. I ended up cutting my lose and selling it 2years later.
Anyways by the sounds of the effort you are putting into finding it, it sounds like you want it back bad, so all the best and hope it all works out in the end and if they don't get it back they atleast the bastard that took it!
