I don't know what's harder, finding a good, trustworthy doctor, or finding a good, trustworthy mechanic. Not being much of a car person myself, I was wary of where to take my car for its standard oil change/inspection. I've heard countless horror stories of people being overcharged, lied to, and upsold on things they never even needed by mechanics. While I approach many things in life with a healthy degree of skepticism, I'd prefer not to have to do so with the well-being of my car.
Back to Basic was near me and at the top of Yelp ratings, so off I went. A couple hours later, they called me to let me know that they'd found a few issues with my car. "Here we go," I initially thought, before they told me that only one of the issues (a cracked serpentine belt) actually needed immediate attention, and would only cost $75 to replace. The other two things could be monitored over the next couple years, and would just need attention eventually. My feeling is that any mechanic that says "it can wait, we just wanted to let you know about it" is probably fairly trustworthy.
As for the serpentine belt, I'd brought in my car fairly late on a Friday, so initially they suggested I just bring it back Monday for the belt replacement. I had a long drive planned for that weekend, and when I told them this, they shuffled around some labor and managed to get it replaced for me before the end of the day so I could make my drive without having to worry about it snapping.
I intend to keep taking my car here for the foreseeable future.
