I went through this not too long ago. Someone attempted to steal my car, couldnt, so they trashed it. I came out of it needing a drivers window, steering column, steering wheel, WHOLE paint job(i have no idea why these clowns scratched it), they also stole my stereo, and a few personal items. My insurance company told me it was probably going to be totaled (86 gn with 150k). I had just recently had motor work done, and a new transmission put it. I told them I would be more than happy to have the vehicle appraised for what its value WAS, they told me they would have someone do it, let me know what its appraised as, and then if I thought it was not fair, have my appraiser do it.
Basically it appraised at 11k. Everything got fixed. It really depends on the condition that your car was in before the incident, and if you have proof of it. The insurance company origionally offered me 3500 and to total it. I sure am glad I turned that more than generous offer down.
