The Pep Boys I go to is the one on 700 E 2100 S Salt Lake City. I've been going there for a couple of years now for parts, oil, and labor on anything I can't fix or don't have time to fix myself.
I have to say that I've been very impressed with the staff at this Pep Boys. They've been knowledgable, polite, and informative every time. I've worked with at least four different people on staff, and they've all been great. What's more is that if they have a deal going on that applies to what I'm getting, they remind me and give me the deal.
I would definitely recommend this Pep Boys to anyone looking for a decent shop.
If you break down on the road, you can even call them and they'll come out with a tow truck and pick you up. It sounds like some people have had bad experiences with other Pep Boys in the area, but as for my Pep Boys, as of August 2014, they're awesome.
