No charge.

I have a Volvo that was mysteriously emitting visible exhaust fumes.  It was mysterious because it was intermittent for a few seconds at a time, few minutes apart.  Also had some rattling in the front.
Brought my car there, and Brian checked it out.  He tightened something and bent something back into place.  Also told me rattling was struts, but nothing dangerous/immediate.   No charge.
I’m just glad they were honest and didn’t try to tell me something bigger was wrong!
