[V8] Rear Ended--Need Parts--To fix or not to fix

[jason.carey@riverrestoration.org]

Audifans, 

Just when I got her running smooth a dog ran out in front of
me and a jeep ran into the back of me.  The body shop
estimated $7K in repairs and I am afraid that the insurance
company is not going to value this car as highly as I do. Any
tips for getting the highest value out of the estimator? 

Its still driveable and I don't suspect any damage other than
body work.  Are there any notorious mechanical problems that
result from a rear end collision?

It was hit pretty directly on the rear right corner and lamp
assembly, the rear right corner is smashed and I need all of
the body parts adjacent to that.  I need to see what parts are
available (I'm in western colorado):

Rt outer panel
Rear body panel
Trunk Lid
Rt trunk side trim
Rt Tail Lamp Assembly
Rt backup lamp assembly
Rt corner moldings upper and lower
Rear Window
Rt glass molding belt
Rear Bumper Cover
Rt Filler side
Right Hinge interior trim 

Poll: Should I fix it? it runs great!

Thanks< Jason
