Finding an auto service shop that you can trust to be competent and fully honest is really important. I used to be nervous taking my car to places for service because I was always afraid they would "invent work". But I'm not nervous taking my car to Zisser's. I feel like they are very straight up with me. One time I elected not to do the repair (i.e. to do it myself at home), and they didn't charge me for their time in trouble shooting the problem, even after I pressed them to let me pay something. They've earned my trust and as a result, I also buy all my tires there.
