Reliable Servicer in South Bay Area
 

I am going to take my Mazda3 2008 sedan to 105 tm service. Could anyone recommend a non bullshit, exchange everything and rip you off service somewhere in the South Bay Area (Silicon Valley, CA)? I dont want anything fancy, just honest guys who fix and service critical items, or what is needed, and not rip you off with things that don't need to be changed.
There are lot of car repair shops, and reading reviews on YELP, but it's really difficult as most of the places have both 5 star and 1 star ratings. Some or really happy with the service, some say "NEVER go to this place!!". Whom to believe, right?
