That looks alot worse than it really is. The impact went over the rear bumper so the rails and trunk floor are not damaged. As far as the rear quarters(fenders) go; the drivers looks to have no damage at all. As far as the passengers quarter, look for any buckles further down the quarter panel (like around the wheel well) If there is none, and the only damage is what you showed in the picture...read on
. After you milk their insurance for all its worth.. here is what you do.
Purchase the following parts...preferably the same color:
Rear bumper cover
trunk lid
taillight set
install the trunk lid and the driver side taillight
remove your bumper cover
At this point you may notice that the trunk lid may not close correctly because the part where the trunk latches on to is pushed back a inch or 2 and will need a "lil pulling" (Not to worry a body shop can easily take car of this)
Now that you have the car looking more "whole" you will need one last part...that part of the passenger quarter which I marked in red in the picture. If you can find a parts car, have them cut that part off outside of my lines to give the body hope as much to work with as possible. When you have this.. head on down to a local body shop. Stay clear of the high priced flashy ones. A small business type will do. Look inside and if things look to be orderly and clean that usually indicates the type of work they will do on your car.
Now what the body shop will do with your car is: First they will remove the damaged part of your quarter, cutting where I drew the doted line and drilling through the spot welds everywhere else. they will than do a lil pulling to have your trunk close correctly and aligned. They will cut off a portion from the part you provided matching the portion they removed from your car and they will weld that in place. Lastly they will apply a little bondo over the straight weld at the dotted line and than prime and paint your quarter providing that you found the other parts the same color.
That is the cheapest Easiest way to fix your problem. the more expensive way is to replace the complete right quarter panel with a new one. Not sure how much they run for our car but usually they tend to be around $600 just the panel and than the labor could be in the thousands. In either event your car is far from totaled having received no real frame damage.
