You could also pick up some carbon fiber panels replace the clams. There's some dealers that post here occasionally that make them.
The biggest worry about this, or any salvage elise is the damage you can't see. How is the frame & tub?
If you're looking at frame damage, you're essentially looking at a parts car.
If you have more time than money though, this might be an interesting project. Although, you would still need money too.
If you do take it on, keep us in the loop like this guy's
thread of awesomeness.
Good luck!
