subrogation claim

My van was totaled when two other vehicles collided, and spun out of control and hit my vehicle while it was waiting at a stop sign. It has been 10 months. None of us had enough coverage (10,000). All 3 vehicles were totaled. Even though my vehicle is still drivable, it was still totaled, because it was cheaper for the at-fault driver's insurance to repay the at cost value than for the property damage. I recently found out that the insurance comp. of the 1st victim that was hit still has their claim in subrogation, and are trying to auction off the vehicle. My vehicle sits in my yard because I was told to remove it from the salvage yard to reduce the storage fees. As I am the 2nd vehicle to be hit by the at-fault driver, it seems that the 1st victim's insurance is stretching this case out a long time. The offending driver's insurance has offered me a settlement, and I accepted. I don't understand why I have to wait for the other victim's insurance to settle if they will get the remaining portion of the claim. Basically if I accept 30% and 70% remains shouldn't that resolve the issue since we're talking about splitting a $10,000 policy? I have been spending a lot of time talking with all of our insurance agencies trying to get this issue resolved, and to remind them that I expect my portion. Hope this makes sense. Any information would be helpful. Thanks.
