I've been going to Zach's Quality Tune-Up in Milpitas for 4-5 years, getting all 3 of our cars serviced. We mostly get oil changes and scheduled services performed there. (I avoid like the plague getting any $$ervice performed at a new-car dealer) Quality Tune-Up's work is at reasonable prices (way less than a dealership), and Zach has always given good advice re what work needs to be done, not always trying to "up-sell" to have more work (or more expensive work) done. I think he's a very honest man, which (at least stereotypically) is unusual in mechanics' shops. He has also been very good, when I've had a car problem that he can't address in his shop, at referring me out to another shop who could perform the work at a very reasonable rate. No, the shop does not have air conditioning in the waiting room (I can't believe that another reviewer expected that!). And yes, the waiting room can also be cool on early winter mornings. But there is a Starbucks and a Black Bear Diner just a block away, which are great places to go if you need to wait a while for service to be completed.
