Did you ever see the car that did the damage? It must have a few dents.
I did not see it, but my understanding was that it was probably repairable. Has to at least get new airbags, though, as well as the front lights. And when you actually get into the details, sometimes what you think isn't so bad is enough to make the repair costs prohibitive.
Going over those rocks, there must have been damage underneath. Exhaust at least, if not rockers, steering, drive train. Or did he just all the rocks out of the way and not gone over.
I'm not sure of the details, since I wasn't even aware that it had happened until four days later. My impression is that the car was far enough onto the wall to get high centered, and they apparently couldn't pull it back, so the tow truck had to go around to the other side of the wall and pull it through. I don't expect I'll ever know any more than that.
