Maybe it's just me, but I don't think I'm alone when I prefer to stay away from corporate owned automotive repair stores.
I somewhat second that, my local Firestone has never treated me wrong (in retrospect), at one point I was told that my battery negative cable that was deeply corroded, I didn't belive the mechanic, and then (a year and some change later) one saturday I need to leave for my welding class, the battery was completely drained. So I throw on the battery charger for ten minutes, the start the car to let it warm up (it 'twas winter), and then it died after 2 minutes, later that day in a diagnostic tear down with my dad we found that indeed the negative cable for the battery corroded to the point that there was no ground for the battery
however, I'm in a permanant feud with a local NTB due to the last experence with them (I get a sense that they all are not like this), this is on two seperate acts that caused me to faith in them, but first let me explain why there betrayal to me has resulted in me never going there again
I used to go to them a lot, they have changed my oil on more than one occasion, did my front&rear sway bar links (the left rear one is now dead, the right rear one is on its way now), shocks and alignment (which I'm pretty sure the warrenty for that is still valid). So, onward to the betrayals, I was told one time when I was in for a no cost alignment (because of the warrenty and that my junior college at the time had so truely awful roads), I was told my brakes were severally worn, for the fronts and backs (pads and rotors) I was quoted $800 for parts and labor. This was the beginning of my yeah+no treatment towards them, through tire rack I purchased carbon ceramic brake pads, OE parking brake shoes and Cenric OE style rotors for a fraction of the price of what I was quoted, one morning I went over to a mechanic buddy's house and installed the fronts (I was still waiting on the rear rotors and the parking brake pads), after taking the pads out we discovered that they weren't worn that much (betrayal #1ish, kind of #0, although I am not too angry about this, taking this as an overconfindent mechanic). About two days later the rear rotors and e brake pads showed up, so I attempted to take my rear wheels off, snapped an extension (I used to go through those like socks before I started buying everything for my ratchets impact grade and/or 1/2" drive), gave up, handed my car off to them, they changed the rear brakes out at a rather low price. Now here's the big one, my car wasn't running right early last year, so I drop it off at the NTB for diagnostics, the following day I get a call from my mom at school and she's ranting off that I'm never aloud to work on my car ever again, I took a class to cool off and develop a counter rant. I had a buddy drop me off at this blasted shop, and my favorite manager (he would frequently give me and memebers of my family huge reductions in labor just out of the fact that I know about as much as my car as any mechanic) was there, we talked, so the jackass mechanic that came up with the diagnosis walks up, so much bullshit, the radiator was installed incorrectly (I still had my OE radiator at the time), the front valve cover was leaking (another shop actually changed it), the motherfucking blinker fluid was leaking AND my intake was installed incorrectly causing oil to leak onto my crankshaft position sensor (which is physically impossible, and as with you guys, my intake is on the other side of the engine bay). The mechanic quickly got the death stare by the manager, he knows that I would frequently work on my own car, still, first one of your employees call me stupid and then call me incompetent, you sir have lost my business for life, however just to fuck with them, when I complete my car (the built engine, manual swap, coil overs...), I want to drop it off to them for diagonostics just to see how they react
