while work gets done, some things are routinely overlooked some small and some that are not so small
a couple examples:
catalytic convertors replaced, had a noticeable exhaust leak afterwards
after fixing a couple engine issues, the service light was not cleared
left some minor pieces of hardware off of some shrouds
In my view they do great with tires, but still need improvement in the engine work department.
We don't do catalytic converters or exhaust work of any kind. We will sub it out if we have a customer that needs it, but that is also rare. If that is the case, and there is a problem, we sure would like to know about it. Unfortunately, you listed yourself anonymously so we have no path to follow up.
