Car may be totaled after repairs

Hello, My wife hit a deer in October of 2007. The car is a 2005 VW Passat TDI that is pretty hard to find. The repair costs have risen from $3000 to over $12000. The car had to go to the dealership for repairs the bodyshop could not do. This week, we found out that the car will not drive and that the transmission needs replacing. The body shop representative said that the insurance company seemed to be in the process of totaling the car. We have not gotten word from the insurance company and they have not returned calls. My question is this: I got a good deal on the car and I'm not andquot;upside downandquot; on it. All of the body work and engine work has been done. Would it be a good decision for me to keep the car, provided the insurance company makes a good offer as to the salvage value and have the transmission repaired or replaced? I keep cars for a long time and have no problem with having a salvage title. What step should I take next?
