Say good bye to a very nice car. Or help me fix it. It was worse in 84

He didnt tighten.
might be just personal syntax, but i use "he" when speaking of a person, and "they" when speaking of a shop

i wonder if the alignment was done by a friend of the OP?
even though that wouldnt change who is legally responsible, it might change how the OP will pursue this
(i know i wouldnt go after a buddy in court like i might a shop)

There is only one person at the shop. The owner. So it was "He" Not "they" That didn't tighten the bolts. The bolts can be tightened by one person. And yes I do know him ."He" Has a shop down the street. We all make mistakes. The car can be replaced and I am OK. I live in a small community and everyone knows each other.
