Some person who shouldn't be driving rear ended my car while I was getting off the freeway, at the light to turn right onto a road. It was a red light and cars were behind me. I was creeping forward to check for traffic, then SLAM I get rear ended by a retired lady who shouldn't be driving (she's telling me about how her husband wont let her drive his car, while he lets the nephew drive it and all her other accidents). I was so upset with the fact that this is a rare car and I let her know about it, her reply in the moment was that I scratched her bumper also.

Any advice dealing with the insurance claim considering this is a Pontiac Solstice no longer in production and without service part support from GM?
I refuse to submit pictures for the insurance claim and plan to have an adjuster come out to see it. In addition, about 10 miles after the accident the in-tank fuel pump shorted out (blowing fuses, measuring pump resistance of 0.4 ohm). Would that be covered by insurance too?
I plan on doing all the repair work myself, however submit that I may have to take it to a body shop to get an estimate to back me up.
Here are parts that are no longer supported by GM and not in stock; based on searches of the GM parts outlets:
1. Rear bumper cover
2. Rear impact bar
3. Rear energy absorber
4. Rear valence
5. Rear brake light, driverside
6. Trunk torque rod
7. Possibly brackets & retainers
The trunk is also shifted over, when you open it, it relaxes to the side overlapping the body a 1/4" / 6mm.
