Had a customer come in yesterday, and tell me that she needed a headlight, and ask if I could install it.
The advice I gave her, doubtless bad, was "You're gonna need to buy a new assembly, and have your mechanic put it in, because someone shot that." No, I didn't trace the bullet's path, because the car was obviously able to drive up like that, so maybe it just hit something that didn't really matter all that much, and stopped.
I no longer really remark on automotive bullet holes.
