Slap some plexi-glass, or better yet, lexan in for a windshield and go play in the woods . . . you wouldn't have to worry 'bout scratches and dents so it should be a blast. I wouldn't drive it out on the road though. Like dubtech said, given the level damage, it wouldn't fair as well in another incident. Unibody vehicles get their strength from their entire structure being one solid piece. The curves and ridges that are stamped into large pannels aren't just there for looks, they are designed in to make the pannels stronger. Dent's and creases in the wrong place make the entire structure subject to collaps at the slightest pressure. About the only way to "heal" it would be find a donor body and put all your mechanicals and interior in it.
Looks like it did it's job though . . . it sacrificed its own body to keep the occupants safe. I just don't think it could do it again. :wink:
